General

Single Interlock Preaction Systems are designed for water sensitive areas that require protection from inadvertent water flow into the sprinkler system piping.

At the heart of Reliable’s Single Interlock Preaction Systems is the Model DDX Deluge Valve. This deluge valve is a hydraulically operated, straight-through-design, differential latching clapper-type (see Fig. 1). System maintenance is simplified since the deluge valve can be reset externally without removing its cover plate. This feature provides a significant system-restoration time advantage. The Model DDX

Deluge Valve has an intermediate chamber and thereby does not require an in-line air check valve. Also, for ease of installation, the deluge valve only requires a single drain connection.

The trim sets for the single interlock preaction systems

(see Figs. 3, 4, 5, 6, 7 and 8) provide all of the necessary equipment for connections to the Model DDX Deluge Valve’s pushrod chamber inlet and outlet ports, a 1¼” (30 mm) main drain on 2” (50 mm), 2½” (65 mm), 76 mm and 3” (80 mm) valve sizes or a 2” (50 mm) main drain on 4” (100 mm), 165 mm, 6” (150 mm) and 8” (200 mm) valve sizes, alarm devices, air supply, and required pressure gauges. The trim sets are available in individual (loose) parts, in time-saving, segmented assembled kit forms or fully assembled to the

Model DDX Deluge Valve (with or without a control valve).

The major benefits of a single interlock preaction system, when compared with a wet pipe or deluge system are as follows:

• A fire alarm sounds prior to the operation of a sprinkler head, which may enable extinguishing the fire by handheld means before the actual operation of any sprinklers and subsequent water damage.

• A trouble annunciator signals whenever the integrity of the piping or sprinklers is accidentally or intentionally disturbed; however, no water flow or water damage will occur at that time.

• Speedy detection and an early fire alarm are provided by fire detectors, without the delay associated with water delivery time in the event of a fire. Note that with a wet pipe system, the fire alarm is delayed until after water has begun flowing from an operated sprinkler head.

Sprinkler piping in Wet Pilot and Electric Actuation Single

Interlock Preaction Systems can effectively be supervised by means of a Reliable Model B-SI Air Compressor Panel or

Model C-SI Air Compressor Panel. Loss of 7 psi (0,5 bar) supervising pneumatic pressure, due to a damaged sprinkler or sprinkler pipe will not cause water to flow through the

Model DDX Deluge Valve and into the system piping. A significant loss of pneumatic pressure will activate a troubleannunciating device when the system pressure falls below approximately 4 psi (0,3 bar). Note: Wherever the word “air” is used in this bulletin as a reference to the pneumatic pressure source it shall also mean “air or nitrogen.”

Wet Pilot Line Single Interlock Preaction Systems use a pilot line consisting of a line of closed sprinklers or pilot line detectors (Reliable’s Model F1-FTR), which are located in the area to be protected. These sprinklers/detectors are more sensitive (lower activation temperature) than the sprinkler heads installed in the fire sprinkler system. The wet pi-

2.

lot line is directly installed to the Model DDX Deluge Valve’s pushrod chamber. Wet pilot line sprinklers are detection devices and do not provide any water to aid in the firefighting capability of the fire sprinkler system.

To fully operate a Wet Pilot Line Single Interlock Preaction

System, the heat from a fire must fuse a wet pilot line sprinkler/detector thereby releasing the water pressure from the

Deluge Valve’s pushrod chamber. As this water pressure is lost in this chamber, the main water supply will open the Deluge Valve’s clapper, thereby flowing water into the fire sprinkler piping. Water flowing into the system will flow through the intermediate chamber of the deluge valve to a mechanical sprinkler alarm (optional) and/or will simultaneously produce water pressure that causes the transfer of contacts in the (optional) alarm pressure switch mounted in the trim. If provided, the alarm pressure switch can electrically initiate the shut-down or start up of equipment, such as computer,

HVAC, or other secondary alarm devices (Note: the wiring contacts for the alarm pressure switch are the “Common” and “A” contacts). The flow of water into the sprinkler system piping converts the dry system into a wet system. In the event that the fire subsequently produces enough heat to operate a fire sprinkler head, water will flow from that sprinkler, controlling or suppressing the fire.

The fire sprinkler system piping may be required to be supervised (see NFPA 13) with air pressure. Loss of this supervisory air due to a damaged sprinkler or the sprinkler piping will not cause the Model DDX Deluge Valve to open. The supervisory air supply for the fire sprinkler piping may effectively be supervised by Reliable’s Model B-SI Air

Compressor Panel or Reliable’s Model C-SI Air Compressor

Panel. Other options include the use of the Reliable NS-PaK or Nitrogen Regulator with an approved nitrogen source, the

Reliable Model A-2 Pressure Maintenance Device with a tank-mounted air compressor, or a tank-less air compressor controlled by a pressure switch or the Reliable Model B-1 Air

Maintenance Device. (See Reliable Bulletin 254).

In Electric Actuation Single Interlock Preaction Sys-

tems, when one electrical detector senses the presence of fire, the electrical releasing control panel activates fire alarm devices and operates the normally-closed solenoid valve

(175 psi (12,1 bar) or 300 psi (20,7 bar) Rated) to the open position (Note: Arranging detectors in a cross-zoned pattern will require operation of two detectors before the solenoid valve can open). The solenoid valve, when closed, retains sufficient water pressure in the pushrod chamber of the

Model DDX Deluge Valve to maintain it closed. Energizing the solenoid valve relieves the water pressure, thus opening the Deluge Valve and allowing water to flow into the sprinkler system.

To fully operate a cross-zoned single interlock system, two electrical detectors must activate and a sprinkler head must open. During the early stages of a fire, smoke or heat activates the first detector, which causes the control panel to produce a local alarm and an alarm at the main fire alarm panel. Electrical relays inside the releasing control panel can be used to shut down air moving equipment or activate security doors and other electrical devices when the panel goes into the first alarm condition. Subsequent activation of

a second, nearby or adjacent, detector will cause the panel to energize the solenoid valve open and release water into the sprinkler system piping. Water flowing into the sprinkler system piping will simultaneously produce water pressure that causes the transfer of contacts in the pressure switch mounted in the Reliable Single Interlock Preaction System’s riser assembly. This pressure switch can electrically initiate the shut down or startup of equipment, such as computers or other second alarm devices. The flow of water into the sprinkler system piping effectively converts the dry system into a wet pipe system. In the event that the fire subsequently produces sufficient heat to operate a sprinkler head, water will flow from that sprinkler, controlling or suppressing the fire.

Dry Pilot Single Interlock Preaction Systems are used in areas that may be subjected to freezing conditions. They can also be utilized to obtain installed sprinkler heights and pipe lengths greater than the allowed for wet pilot systems.

A dry pilot line installation consists of an air-pressurized line of closed sprinklers or pilot line detectors (Reliable’s Model F1-FTR), which are located in the area to be protected.

NFPA 72 or the Authority Having Jurisdiction (AHJ) should be consulted for spacing and elevation requirements for the installation of dry pilot sprinklers/detectors.

In the system’s trim, the dry pilot line is connected to a

Model LP Dry Pilot Line Actuator. This actuator functions very much like a miniature dry pipe valve. It requires only 8 to 28 psi (0,6 to 1,9 bar) of air pressure (depending on the water supply pressure) to maintain the Model DDX Deluge

Valve in a closed position. In areas where moisture-laden air could cause a freezing condition, or other problems in the dry pilot line, the use of a dry, compressed gas such as nitrogen is suggested. Approved gas handling regulators (see

Reliable Bulletin 254) and connections are recommended.

When one of the dry pilot line sprinklers/ detectors actuates, the air pressure in the line is reduced, thus opening the Model LP Dry Pilot Line Actuator, which in turn releases the DDX

Deluge Valve and fills the fire sprinkler piping with water.

However, water does not flow from the fire sprinkler system until one of its sprinklers fuses from the heat of the fire.

The fire sprinkler system piping may be required to be supervised (see NFPA 13) with air pressure. Loss of this supervisory air due to a damaged sprinkler or the sprinkler piping will not cause the Model DDX Deluge Valve to open. This is accomplished by the ½” check valve which is located in the valve’s trim. The check valve prevents air pressure (from the dry pilot line) from escaping out of the Model LP Dry Pilot Line

Actuator. A low air pressure switch (System Sensor EPS40-2 or EPSA40-2) is also provided in the trim. The contacts of this switch will close on the loss of air in the sprinkler piping, thereby providing a low air alarm to aid in insuring the integrity of the sprinkler system piping. The pressure switch’s low air alarm should be wired to a supervisory alarm bell or the building’s alarm system (Note: The wiring for closing of contacts on the loss of pressure is made on the “COM” and

“B” terminals of switch 2.)

Damage to a dry pilot line sprinkler/detector or the dry pilot line piping that causes a significant loss of pressure will cause the Model DDX Deluge Valve to open, flowing water

3.

into the fire sprinkler system piping. The supervisory air supply for both the dry pilot line and the fire sprinkler piping can effectively be maintained by means of pressure-switch-operated, tank-mounted air compressor and a Reliable Model

A-2 Pressure Maintenance Device (see Reliable Bulletins

254). The compressor’s tank provides a reserve supply of air, whereas the Model A-2 Pressure Maintenance Device consistently regulates the air pressure of both the dry pilot line and the fire sprinkler piping.

The dry pilot line sprinklers/detectors must be more sensitive to the heat from a fire than the sprinklers in the fire sprinkler system. The Model F1-FTR (Fixed Temperature Release) is specifically designed for use in dry pilot line operated sprinkler systems. Dry pilot line sprinklers are detection devices and do not provide any water to aid in the firefighting capability of the fire sprinkler system.

To fully operate a dry pilot line preaction system, the heat from a fire must fuse a dry pilot line sprinkler/detector thereby releasing the air pressure from the Model LP Dry Pilot Line

Actuator. The water pressure is then able to overcome the pressure differential of the actuator, allowing water to flow from the Model DDX Deluge Valve’s push rod chamber. As this water pressure is lost in the push rod chamber, the supply pressure will then force the valve’s clapper open, flowing water into the fire sprinkler system piping. Water flowing into the system will flow through the intermediate chamber of the deluge valve to a mechanical sprinkler alarm (optional) and/ or will simultaneously produce water pressure that causes the transfer of contacts in the (optional) alarm pressure switch mounted in the trim. If provided, the alarm pressure switch can electrically initiate the shut-down or start up of equipment, such as computer, HVAC, or other secondary alarm devices (Note: the wiring contacts for the alarm pressure switch are the “Common” and “A” contacts). The flow of water into the sprinkler system piping converts the dry system into a wet system. In the event that the fire subsequently produces enough heat to operate a fire sprinkler head, water will flow from that sprinkler, controlling or suppressing the fire.

System Operation

When set correctly for service, the Model DDX Deluge

Valve is hydraulically established to withhold the supply water from the sprinkler system piping. The Reliable Model DDX

Deluge Valve is shown in both closed and open positions in

Fig. 1. In the closed position, the supply pressure acts on the underside of the clapper and also on the push rod through the push rod chamber’s inlet restriction. The resultant force due to the supply pressure acting on the push rod is multiplied by the mechanical advantage of the lever and is more than sufficient to hold the clapper closed against normal supply pressure surges.

To fully operate (deliver water) a Wet Pilot Line Single Interlock Preaction System, two independent events must coexist before water flow will occur. A wet pilot line sprinkler/detector must fuse along with a fire sprinkler head. Operation of either one of these heads will cause an alarm to annunciate, but will not cause water discharge from the fire sprinkler system piping.

When a fire is detected, the opened wet pilot line sprinkler/ detector vents the push rod chamber to atmosphere through the chamber’s outlet. Since the pressure cannot be replenished through the inlet restriction as rapidly as it is vented, the push rod chamber pressure falls instantaneously. When the push rod chamber pressure approaches approximately onethird of the supply pressure, the upward force of the supply pressure acting beneath the clapper overcomes the leverapplied force thereby opening the clapper.

To fully operate an Electric Actuation Single Interlock Preaction System, two independent events must coexist before water flow will occur. One electrical detector (two detectors in a cross-zoned system) must activate and a sprinkler head must open. Operation of either one of these items will only cause an alarm to annunciate, but will not cause water to discharge from the sprinkler system piping.

When a fire is detected, the energized solenoid valve vents the push rod chamber to atmosphere through the chamber’s outlet. Since the pressure cannot be replenished through the inlet restriction as rapidly as it is vented, the pushrod chamber pressure falls instantaneously. When the pushrod chamber pressure approaches approximately one-third of the supply pressure, the upward force of the supply pressure acting beneath the clapper over comes the lever-applied force thereby opening the clapper.

In all Reliable Single Interlock Preaction Systems, once the clapper has opened, the lever acts as a latch, preventing the clapper from returning to the closed position. Water from the supply flows through the Deluge Valve into the system piping. Water also flows through the Deluge Valve alarm outlet to the alarm devices.

After system shutdown, resetting the Model DDX Deluge

Valve is quite simple. Doing so only requires pushing in and turning the reset knob at the rear of the valve (see Fig 1).

The external reset feature of the Model DDX Deluge Valve provides a means for simple, economical system testing, which is one essential facet of a good maintenance program.

The external reset feature does not, however, eliminate another important facet of good maintenance, namely, periodic cleaning and inspection of the internal valve parts.

In the event that water builds up inside the valve due to condensate from the air supply system or water left inside from valve system testing, a drain is available for venting. After closing the main supply valve, a small valve over the drain cup can be opened slightly until the water inside the valve body and the main pipe column has drained. See the section titled “Draining Excess/Condensate Water From System” in this bulletin for the detailed procedure.

The Model B Manual Emergency Station (see Fig. 12) is also included in all Reliable Single Interlock Preaction System trim sets. It consists of an aluminum nameplate mechanically attached to a ball valve. The valve handle in its OFF position is guarded against accidental turning to the ON position (and system discharge) by a nylon cable tie provided with each trim kit. The cable tie is inserted, as shown in Fig. 12, after the system has been restored for operation. The nylon cable tie is designed to allow, in case of an emergency, forceful turning of the valve handle to the ON position. As an alternative to the Model B Hydraulic Manual Emergency Station, the Model

A Hydraulic Manual Emergency Pull Box (see Reliable Bulletin 506) is also available and can be provided as an option.

Whenever ambient temperature conditions are high, the water temperature in the Model DDX Deluge Valve’s pushrod chamber could possibly increase, thereby increasing the pressure in the chamber to values exceeding the rated pressure of the system. In an indoor installation where standard room temperatures are exceeded, a pressure relief kit may be needed. Pressure relief kit, P/N 6503050001, can be installed into the pushrod chamber’s releasing line to limit the pressure to 250 psi (17,2 bar).

Pressurizing Line Connection

The water supply for the push-rod chamber must be provided by connection of its inlet pressurizing line to the water supply piping. Pressurizing lines for multiple Model DDX

Deluge Valve push-rod chambers must never be manifolded together, having only a single tap on the water supply piping. Each Model DDX Deluge Valve must have its own push-rod chamber pressurizing line connection.

This connection must be made on the supply side of the water supply control valve (see Fig. 7 or Fig. 8). This can be accomplished by:

• Using a tapped connection directly below or next to the main water supply control valve using a welded outlet or the appropriate mechanical fittings. A grooved-end outlet coupling is one way to achieve this; or

• Using a water supply control valve that has an available threaded (NPT) supply-side tap design to allow for a direct water supply connection to the Model DDX Deluge

Valve’s push-rod chamber.

Caution: Reliable’s DDX valve is designed with an inlet restriction built into the pushrod chamber. It is important not to introduce additional restrictions into the direct water supply connection or the discharge from the pushrod chamber by installing additional valves or improperly installing the copper lines used in the trim of the valve.

Hydrostatic Testing of DDX Valves and DDX

Systems

As required by NFPA 13, fire sprinkler systems with working pressures up to and including 150 psi are to be hydrostatically tested at a water pressure of 200 psi and maintain that pressure without loss for two hours. Fire sprinkler systems with working pressures above 150 psi are required to be hydrostatically tested at 50 psi above the system working pressure and maintain that pressure without loss for two hours. In addition to the hydrostatic tests described above, dry pipe and double interlock preaction systems require an additional low pressure air test.

In some cases, hydrostatic testing (in accordance with the

NFPA 13 requirements noted above) will result in pressures that exceed the working pressure of the valve and trim kit for the two-hour test period. The valve and applicable trim kit have been tested, approved and listed under these conditions and as such, hydrostatic testing in accordance with NFPA 13 is acceptable. In addition, the clapper can remain in the closed position and the trim kit need not be isolated, as each has been designed to withstand hydrostatic testing as required by NFPA 13.

Hydrostatically testing the valve and trim to pressures higher than their rating is limited to the hydrostatic test as referenced by NFPA 13. It does not address the occurrence(s) of a “water hammer” effect, which can indeed damage the valve. A “water hammer” in the water supply piping of the valve can create pressures in excess of the rated pressure and should be avoided by all necessary means. This condition may be created from improper fi re pump settings, underground construction work, or an improper venting of trapped air in the water supply piping.

19.

System Design Considerations

The automatic sprinklers, wet pilot line sprinklers/ detectors, and signaling devices which are utilized with the Wet

Pilot Line Single Interlock Preaction System must be UL or

ULC Listed, as applicable.

The automatic sprinklers, air compressor, releasing devices, electric releasing control equipment, fire detection devices, manual pull stations, and signaling devices which are utilized with the Electric Actuation Single Interlock Preaction System must be UL or ULC Listed or FM Approved, as applicable.

The automatic sprinklers, air compressor, releasing devices, electric releasing control equipment, fire detection devices, manual pull stations, and signaling devices which are utilized with the Dry Pilot Line Single Interlock Preaction

System must be UL or ULC Listed, as applicable.

The Deluge Valve, and all interconnecting piping must be located in a readily visible and accessible location and in an area that can be maintained at a minimum temperature of

40°F (4°C). Note: Heat tracing is not permitted.

Pendent sprinklers, other than dry pendents, used on preaction systems shall be installed on return bends per NFPA

13.

In Electric Actuation Single Interlock Preaction Systems, the solenoid valve is operated and supervised by the electrical releasing/control panel.

In Wet Pilot Line Single Interlock Preaction Systems, the wet pilot line is only a detection system and does not contribute to controlling the fire. Its installation is subject to the following restrictions: a. It is not to be installed in an area subject to freezing.

b. It is not to be installed in an area where temperatures in excess of 150°F (65°C) are anticipated.

c. NFPA 72 or the authority having jurisdiction should be consulted for spacing and elevation requirements.

d. Maximum wet pilot line length and height must comply with data provided in Fig. 2.

System Air Pressure Requirements

For Wet Pilot Single Interlock Preaction Systems and

Electric Actuation Single Interlock Preaction Systems, a

Reliable Model B-SI Air Compressor Panel or Reliable Model C-SI Air Compressor Panel can be used to maintain the system air pressure at approximately 7 psi (0,5 bar). The air compressor panels contain an integral low air pressure warning light.

In some circumstances, such as when dry sprinklers are being used in a preaction system, it may be desirable to supervise the preaction system at air pressures higher than 7 psi (0,5 bar). For such cases, Reliable recommends the use of a tank-mounted compressor and the Reliable Model A-2

Pressure Maintenance Device. Supervising pressure may be between 7 psi and 20 psi (0,5 and 1,4 bar).

For Dry Pilot Line Single Interlock Preaction Systems, a Reliable Model A-2 Pressure Maintenance Device can be used to maintain the pneumatic pressure of both the Dry

Pilot Line of detectors and the fire sprinklers to the values shown in Table A. The values listed in the table represent the necessary ranges of pneumatic pressure required to keep the Model LP Dry Pilot Line Actuator in the closed position for a given water supply pressure.

Note: During system set-up, a higher pneumatic pressure may be required in order to properly set the Model

LP Dry Pilot Line Actuator.

Whenever multiple systems area supplied by a common air or nitrogen source, each system must have its own pressure maintenance device for individual maintenance of pressure (NFPA 13, 7.2.6.5).

System Electrical Requirements

When Using the Electric Actuation Single Interlock Preaction System, all releasing, alarm and detection devices in the Single Interlock Preaction System are supervised by the Potter PFC-4410-RC Releasing Control Panel. Connect these devices as shown in Fig. 9. The Releasing/ Control

Panel should be set to use Program #6 (See Potter Instruction Manual #5403550).

The power supply, the standby emergency power supply, battery charger, and the rectifier circuitry are all contained within the Potter PFC-4410-RC Releasing Control Panel. The solenoid valve is operated and supervised by the Potter

PFC-4410-RC Releasing Control Panel. Potter PFC-4410-

RC Releasing Control Panel requires 120 VAC. Batteries that provide ninety hours of standby power are required for Factory Mutual Approved systems.

Note:

In order for the solenoid valve to maintain Reliable’s warranty it must remain sealed as it came from the factory. If there are concerns about the valve’s internal components, immediate replacement is recommended.

Trim Descriptions

The Single Interlock Preaction Trims for the Reliable Model

DDX Deluge Valve are arranged for rapid, easy, and compact attachment, and serve as connection points to Reliable

Model C Mechanical Alarms and other devices.

The available Model DDX Single Interlock Preaction System trim sets are:

• Wet Pilot Line Single Interlock Preaction Trim

• Dry Pilot Line Single Interlock Preaction Trim

• Electric Actuation Single Interlock Preaction Trim

All three trim configurations can be ordered as individual parts, in time-saving segmentally assembled kit forms, or fully assembled to the Model DDX Deluge Valve (with or without a control valve).

The Model B Hydraulic Manual Emergency Station (see

Fig. 12) is a standard item of all Deluge Valve trim sets. It consists of an aluminum nameplate mechanically attached to a ball valve. The valve handle in its OFF position is guarded against accidental turning to the ON position (and system discharge) by a nylon cable tie provided with each trim kit. The cable tie is inserted, as shown in Fig. 12, after the system has been restored for operation. The nylon cable tie is designed to allow, in case of an emergency, forceful turn-

Model A Hydraulic Manual Emergency Pull Box (see Bulletin

506) is also available and can be provided as an option.

Model F1-FTR fixed temperature pilot line detectors and spacing requirements are described in Bulletin 180.

Maintenance

Reliable Single Interlock Preaction Systems and associated equipment shall periodically be given a thorough inspection and test. NFPA 25, Inspection, Testing and Maintenance of Water Based Fire Protection Systems, provides minimum maintenance requirements. System components shall be tested, operated, cleaned, and inspected at least annually, and parts replaced as required.

Wet Pilot Line Single Interlock Preaction Trim

Wet pilot line single interlock preaction trim operation is a simple method of Deluge Valve Actuation. The trim contains components such as a one and one quarter main drain on

2” (50 mm), 2½” (65 mm), 76 mm and 3” (80 mm) valve sizes or a two inch main drain on 4” (100 mm), 165 mm,

6” (150 mm) and 8” (200 mm) valve sizes, alarm test, supply and push rod chamber pressure gauges, and push rod chamber connections. The wet pilot line consists of a line of closed detectors (Model F1-FTR) located over the area to be protected. This line contains water under pressure and is connected to the outlet of the push rod chamber of the Deluge Valve. When one of the pilot line detectors actuates, the push rod chamber is vented and the Deluge Valve operates.

The Deluge Valve can also be operated manually by opening the ball valve of the Model B Hydraulic Manual Emergency Station (see Fig. 12) or the optional Model A Hydraulic

Manual Emergency Pull Box (see Reliable Bulletin 506).

The wet pilot line is only a detection system and does not contribute to controlling the fire. Its installation is subject to the following restrictions: a) It is not to be installed in an area subject to freezing.

b) It is not to be installed in an area where temperatures in excess of 150°F (65°C) are anticipated.

c) NFPA 72 or the authority having jurisdiction should be consulted for spacing and elevation requirements.

d) Maximum wet pilot line length and height must comply with data provided in Fig. 2.

Wet Pilot Trim installation on Model DDX Deluge Valves uses eight tapped openings for trim connections. Each opening and its function are indicated on Fig. 3 or Fig. 4.

Using Fig. 3 or Fig. 4 as reference, the recommended trim installation is as follows:

Electric Actuation Single Interlock Preaction

Trim

Electric Actuation trim (see Figures 5 and 6) combines a normally closed/powered-open solenoid valve with the Wet

Pilot Line Single Interlock Preaction Trim for releasing the

Deluge Valve. The solenoid valve used in the assembly is available in either a 175 psi (12,1 bar) or 300 psi (20,7 bar) rating.

Note:

In order for the solenoid valve to maintain Reliable’s warranty it must remain sealed as it came from the factory. If there are concerns about the valve’s internal components, immediate replacement is recommended.

Electric Actuation Trim installation on Model DDX Deluge

Dry Pilot Line Single Interlock Preaction Trim

Dry pilot line single interlock preaction trim is used in water sensitive areas which are subject to freezing conditions or to obtain installed sprinkler heights and pipe lengths greater than allowed for wet pilot line trim.

Dry pilot operation uses a pilot line of closed sprinklers

(Model F1-FTR) containing air under pressure located in the

27.

area to be protected. This pressurized line is connected to a

Model LP Dry Pilot Line Actuator. The dry pilot line actuator functions very much like a miniature dry pipe valve. In areas where moisture-laden air could cause freezing or other problems in the dry pilot line, the use of a cylinder of dry compressed gas such as nitrogen is suggested. Approved gas handling regulators and connections are then recommended. When one of the closed sprinklers on the dry pilot line actuates, the air pressure is reduced, thus opening the

Model LP Dry Pilot Line Actuator, which releases the Deluge

Valve. NFPA 72 or the Authority Having Jurisdiction should be consulted for spacing and elevation requirements of the pilot line sprinklers.

The Dry Pilot Line Trim, shown in Figures 7 and 8, includes gauges to read the air and water pressure, a low air pressure switch, a pressure relief valve, a Model LP Dry Pilot Line

Actuator, and connections for the dry pilot line of detectors.

Dry Pilot Line Trim installation on Model DDX Deluge Valves uses eight tapped openings for trim connections. Each opening and its function are indicated on Fig. 7 and Fig. 8.

Using Fig. 7 and Fig. 8 as reference, the recommended trim installation is as follows:

1. Install ½” nipple (#39, Fig. 7 or #41, Fig. 8) in tapped opening marked “TEST”. Note: If interference occurs between the supply gauge and the control valve, the 1/4” plug

(#58, Fig. 7 or #58, Fig. 8) in the opening marked “SUP-

PLY” may be swapped with: the 1/4” nipple (#37, Fig. 7), angle valve (#11, Fig. 7) and gauge (#73, Fig. 7) for the

2” (50mm), 2-1/2” (65mm), 76mm and 3” (80mm) valve sizes; 1/4” nipple (#36, Fig. 8), 1/4” elbow (#27, Fig. 8),

1/4” nipple (#37, Fig. 8), 3-way valve (#70, Fig. 8) and the gauge (#72, Fig. 8) for the 4” (100mm), 165mm and

6” (150mm) valve sizes; 1/4” nipple (#37, Fig. 8), 3-way valve (#70, Fig. 8) and the gauge (#72, Fig. 8) for the 8”


2. Install ½” nipple (#42, Fig. 7 or #38, Fig. 8) in tapped opening marked “ALARM” and connect balance of this trim line.

3. Install ¼” plug (#58, Fig. 7 or #58, Fig. 8) in tapped opening marked “SUPPLY.” Note: If interference occurs between the supply gauge and the control valve, the 1/4” plug

(#58, Fig. 7 or #58, Fig. 8) in the opening marked “SUP-

PLY” may be swapped with: the 1/4” nipple (#37, Fig. 7), angle valve (#11, Fig. 7) and gauge (#73, Fig. 7) for the

2” (50mm), 2-1/2” (65mm), 76mm and 3” (80mm) valve sizes; 1/4” nipple (#36, Fig. 8), 1/4” elbow (#27, Fig. 8),

1/4” nipple (#37, Fig. 8), 3-way valve (#70, Fig. 8) and the gauge (#72, Fig. 8) for the 4” (100mm), 165mm and

6” (150mm) valve sizes; 1/4” nipple (#37, Fig. 8), 3-way valve (#70, Fig. 8) and the gauge (#72, Fig. 8) for the 8”


4. Install ½” nipple (#38, Fig. 7 or #38, Fig. 8) in tapped opening marked “OUT” and connect balance of this trim line.

5. Install ¼” inline check valve (#17, Fig. 7 or #16, Fig. 8) in tapped opening marked “IN” and connect balance of this trim line. Caution: Over tightening check valve can cause a restriction in flow that may prevent the valve from “setting up”.

6. Install 1¼” Nipple (#48, Fig. 7) or 2” nipple (#48, Fig. 8) in tapped drain opening and connect balance of this trim line.

7. Install ¾” x ¼” reducing bushing (#53, Fig. 7 or #53, Fig. 8) in the lower-most tapped opening at the rear of the Deluge

Valve and connect the balance of this trim line.


Connect the air supply to the air inlet side of the Model LP

Dry Pilot Line Actuator as shown in Fig. 7 or Fig. 8. Table

A specifies the air pressure to be used in a dry pilot line.

The level of air pressure is adjusted by removing the cap nut on the end of the Relief Valve (#56, Fig. 7 or #56, Fig. 8) and turning the now exposed slotted adjusting screw clockwise to increase pressure or counterclockwise to reduce it.

Replace the cap nut after the correct pressure setting has been made at 5 psi above the maximum pilot line pressure required by Table A. An appropriate automatic pressure maintenance device must be used to safeguard against the

Deluge Valve tripping due to air pressure leaks in the dry pilot line. See Bulletin 254 for pressure maintenance device information.

Install the dry pilot line as required. Wire the low air pressure switch (#5, Fig. 7 or #5, Fig. 8) to an annunciating device or control panel. This low air pressure switch should be set to open at an air pressure which is slightly lower than the

“Not Less Than” values found in Table A.

Maintenance – Model LP Dry Pilot Line Actuator

Refer to Figs. 11 & 15

If water constantly flows through the Model LP Dry Pilot

Line Actuator and into the drain, there is a leak in the seal of the Actuator’s seat.

1. Close the main valve controlling water supply (Fig. 15) to the Dry Pipe Valve and close off the air/nitrogen supply to the sprinkler system. Close valve A (Fig. 15).

2. Drop pressure in the system by opening the ¼” globe valve, valve E (Fig. 15), and remove the Actuator from the system.

3. Remove all six bolts (#9, Fig. 11) holding the Actuator together. Clean or replace the facing plate assembly (#5, Fig.

11) and seat (#3, Fig. 11).

4. Reassemble the Actuator, using a torque of 8 ft-lbs on the facing plate nut (#7, Fig. 11) and 12 ft-lbs on the six bolts

(#9, Fig. 11). Use a cross-tightening pattern. Reinstall the

Actuator. Set up the Model DDX Deluge Valve as per the section “Resetting Model DDX Deluge Valve System”.

Resetting Model DDX Deluge Valve Single

Interlock Preaction Systems

Refer to Figs. 7, 8, 13, 14 & 15.

1. Close the valve controlling water supply (Fig. 15) to the

Deluge Valve and close off the air supply to the sprinkler system.

2. Close the pushrod chamber supply valve, valve A (Fig. 15).

3. Open main drain valve B (Fig. 15) and drain system.

4. Open all drain valves and vents at low points throughout the system, closing them when flow of water has stopped.

Open valve D (Fig. 15). Note: The above steps accomplish the relieving of pressure in the pushrod chamber of the Deluge Valve.

5. With valve F (Fig. 15) open, push in the plunger of ball drip valve G (Fig. 15), forcing the ball from its seat, and drain the alarm line.

6. With the Model B Manual Emergency Station, valve D (Fig.

15) open, push in and rotate the Deluge Valve’s external reset knob (#14, Fig. 13 or #38, Fig. 14) clockwise, until you hear a distinct noise indicating that the clapper has reset.

7. Inspect and replace any portion of the detection system and/or sprinkler system subjected to fire conditions.

8. Open valve A (Fig. 15) and allow water to fill the push rod chamber. Close valve D (Fig. 15).

9. Bleed all air from the actuation piping.

A. Wet Pilot Line Single Interlock Preaction Trim—bleed the entire wet pilot line until all air is removed at the most remote sprinkler.

B. Electric Actuation Single Interlock Preaction Trim— open the solenoid valve by operating a detector or an electric manual emergency station. While water is flowing through the solenoid valve, cause it to close using the release control panel reset.

C. Dry Pilot Line Single Interlock Preaction Trim—open valve D (Fig. 15) allowing water to flow through the pilot line actuator. When all air has been expelled from the release line, and there is a solid flow of water into the drain cup H (Fig. 15), apply compressed air or nitrogen through the pressure maintenance device to close the pilot line actuator. Subsequently, close valve

D (Fig. 15) or (#7, Fig. 7 or #7, Fig. 8) and adjust the air or nitrogen pressure to the appropriate value in

Table A as indicated on air pressure gauge (#72, Fig.

7 or #71, Fig. 8).

10. Close valve F (Fig. 15). Open the valve to restore air pressure in the sprinkler system. Note: To build supervisory air pressure in the sprinkler system, it may be necessary to temporarily close the main drain valve, valve

B until air pressure has built up to the manufacturers recommended levels.

11. Open valve F (Fig. 15). Verify the main drain valve, valve

B is open. Open slightly the main valve controlling water supply (Fig. 15) to the Model DDX Deluge Valve, closing drain valve B (Fig. 15) when water flows. Observe if water leaks through the ball drip valve, valve G (Fig. 15), into the drip cup, H (Fig. 15). If no leak occurs, the Deluge Valve’s clapper is sealed. Open slowly and verify the main valve controlling water supply is fully opened and properly monitored.

12. Verify that valve A (Fig. 15) and valve F (Fig. 15) are open.

Valve A (Fig. 15) must remain open when the Deluge

Valve has been reset, to maintain water pressure in the push rod chamber.

13. Verify that the Model B Manual Emergency Station, valve D

(Fig. 15) is secured in the OFF position with the appropriate nylon tie (#57, Fig. 7 or #57, Fig. 8) see Fig. 12.

Inspection and Testing

Refer to Figs. 13, 14 & 15.

1. Water supply — be sure the valves controlling water supply to the Deluge Valve are opened fully and properly monitored.

2. Alarm line — be sure that valve F (Fig. 15) is opened and remains in this position.

3. Other trimming valves — check that valve A (Fig. 15) is open, as well as all of the pressure gauge’s ¼“ 3-way valves. Valves D, E & J (Fig. 15) should be closed.

4. Ball drip valve G (Fig. 15) — Make sure valve F (Fig. 15) is open. Push in on the plunger to be sure ball check is off its seat. If no water appears, the Deluge Valve’s water seat is tight. Inspect the bleed hole (see Fig. 13 or Fig. 14) on the underside of the push rod chamber for leakage.

5. Dry pilot trim — check air gauge pressure for conformance to Table A.

6. Wet pilot and Electric Actuation trim — check that system air pressure is approximately 7 psi (0,5 bar). Check the pressure maintenance device for leakage and proper pressure.

7. Releasing device — check outlet of the releasing device

(i.e., the dry pilot line actuator, solenoid valve, or the hydraulic manual emergency station) for leakage. Also verify that tubing drain lines from releasing devices are not pinched or crushed which could prevent proper releasing of the Deluge Valve.

8. Testing alarms — Make sure valve F (Fig. 15) is open.

Open valve J (Fig. 15) permitting water from the supply to flow to the electric sprinkler alarm switch and to the mechanical sprinkler alarm (water motor). After testing, close this valve securely. Push in on the plunger of ball drip valve

G (Fig. 15) until all of the water has drained from the alarm line.

9. Operation test — Open the Model B Manual Emergency

Station, valve D (Fig. 15).

Note: An operational test will cause the Deluge Valve to open and flow water into the sprinkler system.

10. Secure the Model B Manual Emergency Station, valve D

(Fig. 15), in the OFF position with nylon tie after Deluge

Valve is reset (see Fig. 12).

Testing Detection System Without Operating

Deluge Valve

Refer to Figs. 7, 8 & 15.

1. Close the valve controlling water supply to Deluge Valve and open the main drain valve B (Fig. 15).

2. Verify that valve A (Fig. 15) is open, allowing water to enter the push rod chamber.

3. Operate detection system —

A. Wet Pilot Line Single Interlock Preaction Trim—open

Model B Manual Emergency Station, valve D (Fig.

15).

B. Dry Pilot Line Single Interlock Preaction Trim—directly above the Model LP Dry Pilot Line Actuator, remove the ¼” pipe plug (#58, Fig. 7 or #58, Fig. 8) and open the ¼” three-way valve (#71, Fig. 7 or #70, Fig. 8) until the Model LP actuator operates. This will be indicated by a sudden drop in water pressure on the Deluge

Valve’s pushrod chamber gauge. The operation of the actuator will vent the pushrod chamber of the Deluge Valve and cause the valve’s clapper to open.

C. Electric Actuation— energize the solenoid valve by operating a detector (or detectors if cross-zoned).

4. Operation of the detection system must result in a sudden drop of water pressure in the push rod chamber.

5. Reset detection system — reverse operations performed in step three above and then proceed according to the directions listed in the “Resetting Model DDX Deluge Valve

Single Interlock Preaction Systems” section of this bulletin for resetting the Deluge Valve.

Draining Excess/Condensate Water From

System

Refer to Fig. 15

1. Close the main valve controlling water supply to Deluge

Valve. Also close valve A and open main drain valve B.

2. Open condensate drain valve E until all water has drained.

Close valve E. Note: Be sure not to keep valve E open for an extended period of time because that will cause enough system air to bleed off thereby causing an undesirable activation of a trouble-annunciating device.

3. Close main drain valve B. If system contains pressurized air, allow air pressure to come back up to specification.

Open valve A first, and then open the main valve controlling the water supply to the Deluge Valve.

Maintenance Procedures - Model DDX Deluge

Valve

Refer to Figs. 7, 8, 13, 14 & 15.

5. Mechanical sprinkler alarm (water motor–not shown)

not operating: This is most likely caused by a clogged screen in the strainer of the water motor. Proceed as follows: Remove plug from the strainer. Remove and clean the screen. Replace the screen and the plug, and then tighten securely (Ref. Bulletin 613).

6. Leakage out of the ball drip valve G (Fig. 15).

a. Water leakage due to water column in deluge systems:

This condition can be caused by leakage past the system side of the Model DDX Deluge Valve’s seal assembly

(#8, Fig. 13 or #5, Fig. 14). Be sure that this surface is free of any type of debris. To eliminate leakage due to water column in a deluge system, refer to the section in this bulletin marked “Draining Excess/Condensate Water

From System”. If the problem continues proceed to the following section.

b. Leakage, air or water from the ball drip valve,

G (Fig. 15):

If system air is leaking out the ball drip valve, the problem is either damage to the airside of the Model DDX Deluge

Valve’s seal assembly (#8, Fig. 13 or #5, Fig. 14), seat

(#29, Fig. 13 or #2, Fig. 14), the upper seat o-ring (#23,

Fig. 13 or #11, Fig. 14) or, on the 8” (200 mm) valve size only, the mounting ring o-ring (#2, Fig. 13). If supply water is leaking out the ball drip valve, the problem could be caused by damage to the Model DDX Deluge Valve’s seal assembly (#8, Fig. 13 or #5, Fig. 14), seat (#29, Fig.

13 or #2, Fig. 14), or lower seat O-ring (#24, Fig. 13 or

#11, Fig. 14). The following section provides instructions to correct both conditions:

A) Shut down the valve controlling the water supply to the Deluge Valve and open the

1¼” main drain valve on the 2” (50mm), 2½”

(65mm), 76mm and 3” (80mm) valve sizes or the 2” main drain valve on the 4” (100mm),

165mm, 6” (150mm) and 8” (200mm) valve sizes, valve B (Fig. 15). Open the water column drain valve E (Fig. 15). Close the pushrod chamber supply valve A (Fig. 15) and open the Model B Manual Emergency Station, valve D (Fig. 15).

B) Remove the Deluge Valve’s front (handhold) cover (#7, Fig. 13 or #4, Fig. 14) and inspect the seat (#29, Fig. 13 or #2, Fig. 14), clapper

(#6, Fig. 13 or #3, Fig. 14), and seal assembly (#8, Fig. 13 or #5, Fig. 14) for damage. If inspection indicates damage to the seal assembly (#8, Fig. 13 or #5, Fig. 14), replace as follows:

For Valve Sizes: 2” (50mm), 2½” (65mm),

76mm, 3” (80mm), 8” (200mm) and 4”

(100mm), 6” (150mm) & 165mm with Screw-In

Seat only, Refer to Fig. 7, Fig. 8 & Fig. 13:

Remove the bumpstop nuts (#10, Fig. 13) and remove the seal assembly (#8, Fig. 13). Install a new seal assembly (#8, Fig. 13) and thread the bumpstop nuts (#10, Fig. 13) onto the threaded studs of the seal assembly (#8, Fig. 13) and tighten finger tight plus ¼ to ½ turn. If inspection indicates damage to the clapper (#6, Fig. 13) only, then the clapper subassembly can be removed as follows:

At the rear of the valve, disconnect the water column drain trim section starting with the elbow connector (#22, Fig. 7 or #21, Fig. 8). Then remove the ¼” globe valve (#33, Fig. 7 or #32,

Fig. 8), followed by the ¾”x¼” reducing bushing

(#53, Fig. 7 or #53, Fig. 8). Remove the retaining ring (condensate drain side for 2” (50mm),

2½” (65mm), 3” (80mm), 76mm and 8” (200mm) valve sizes or hand hole cover side for 4”

(100mm), 6” (150mm) and 165mm valve sizes) from the clapper hinge pin (#30, Fig. 13) and push this pin through the hand hole opening for

2” (50mm), 2½” (65mm), 3” (80mm), 76mm and

8” (200mm) valve sizes or condensate drain side for 4” (100mm), 6” (150mm) and 165mm valve sizes and remove the clapper subassembly. Replace the seal assembly as described previously.

Inspect the clapper (#6, Fig. 13) visually before reinstalling. Reinstall in the reverse order making sure the clapper spacers are in their proper position. If the seat (#29, Fig. 13) is damaged or it is suspected that the leakage is through the lower

O-ring (#24, Fig. 13), the seat-clapper subassembly is easily removed as a unit as follows:

35.

Using Reliable P/N 6881603000 Seat Wrench for

2” (50mm), 2½” (65mm), 76mm and 3” (80mm) valve sizes, Reliable P/N 6881604000 for 4”

(100mm) valve size, Reliable P/N 6881606000 for the 6” (150mm) and 165mm valve sizes or

Reliable P/N 6881608000 Seat Wrench for 8”

(200mm) valve size, remove the seat by unscrewing. This will loosen the seat-clappermounting ring subassembly. Reach into the valve and grasp the seat and remove it from the valve. Then remove the clapper-mounting ring subassembly from the valve. Visually examine all components of the seat-clapper-mounting ring subassembly replacing any component that appears damaged. New O-rings (#23 & #24, Fig.

13 and #2, Fig. 13 (8” (200mm) valve size only)) should always be used for reassembly.

For Valve Sizes: 4” (100mm), 165mm, 6”

(150mm) with Drop-In Seat Confi guration only, Refer to Fig. 8 and Fig. 14:

At the rear of the valve, disconnect the water column drain trim section starting with the elbow connector (#21, Fig. 8). Then remove the

¼” globe valve (#32, Fig. 8), followed by the

¾”x¼” reducing bushing (#53, Fig. 8). Remove the retaining ring (hand hole cover side) from the clapper hinge pin (#14, Fig. 14) and push this pin through the condensate drain port and remove the clapper subassembly. Remove the four retaining screws (#24, Fig. 14) holding the seal faceplate assembly (#5, Fig. 14). Inspect the clapper (#3, Fig. 14) visually before installing.

Apply a small amount of silicone based lubricant to the four retaining screws. Install a new seal faceplate assembly. Torque the retaining screws to approximately 40 inch-pounds and reassemble. If the seat (#2, Fig. 14) is damaged or it is suspected that the leakage is through the lower o-ring (#11, Fig. 14), the seat-clapper subassembly is easily removed as a unit as follows:

Using a 5/16” Allen wrench, remove the two 3/8”

NPT pipe plugs (#19, (not shown) Fig. 14) located on the side chamber side of the Model DDX deluge valve. The seat-clapper subassembly is retained by two locking pins (#17, (not shown)

Fig. 14). The centers of these pins have a ¼”-20 threaded hole. Remove the two locking pins by engaging them with a ¼”-20 screw and pulling them out (the two locking pins are not externally threaded, so turning them with the attached ¼”-

20 screw or threaded rod is not recommended. A proven method is to use ¼”-20 threaded rod with a locknut on the unassembled end. Grab hold of the locknut with a pliers or vise-grips and tap the pliers or vise-grips in the direction away from the

Deluge Valve. Doing so should pull the locking pins out of the Deluge Valve. With the clapper

(#3, Fig. 14) in the closed position (not latched), dislodge the clapper-seat subassembly from the

36.

valve body by inserting two slotted screwdrivers under the lever and clapper mounting ears and pry up until the clapper-seat subassembly is free from its bore. Reach into the valve and grasp the clapper-seat subassembly from the sides.

Making sure the clapper is in the closed position

(see Fig. 1), lift up and rotate the clapper-seat sub assembly clockwise 90 degrees so that the lever side of the assembly is facing up towards the outlet of the deluge valve. Next, rotate the clapper-seat sub assembly 90 degrees about the centerline of the valve so that the clapper is facing the hand hole opening and the lever is still facing the outlet of the deluge valve. Then rotate the clapper-seat sub assembly 90 degrees, so that the clapper is now facing the outlet of the deluge valve and the lever is now facing the back of the valve. Pull the clapper-seat sub assembly out through the hand hole opening by the hinge pin side. Rotating the seat-clapper subassembly up as it is being removed will help it slide out more easily since the lever will prohibit it from sliding straight out. Visually examine all components of the clapper-seat subassembly replacing any component that appears damaged. New orings (#11, Fig. 14) should always be used for reassembly.

Reassembly

:

For Valve Sizes: 2” (50mm), 2½” (65mm),

76mm, 3” (80mm), 8” (200mm) and 4”

(100mm), 6” (150mm) & 165mm with Screw-In

Seat Confi guration only, Refer to Fig. 13:

Clean the bore of the valve body. Lubricate the bore with O-ring grease. Lubricate and install the

O-rings (#23 & #24, Fig. 13) onto the seat. Lubricate and install the mounting ring o-ring (#2, Fig.

13) into the body (8” (200mm) valve size only). Insert the clapper-mounting ring subassembly into the handhold opening of the Deluge Valve using caution to not damage or dislodge the mounting ring o-ring (#2, Fig. 13)(8” (200mm) valve size only). Align the mounting ring so that the Lever

(#15, Fig. 13) is near the pushrod (#25, Fig. 13) and the mounting ring (#5, Fig. 13) “ears” are between the tabs of the valve body (#1, Fig. 13). Insert the seat (#29, Fig. 13) into the valve body (#1,

Fig. 13) and through the clapper-mounting ring subassembly. Start to tread the seat (#29, Fig.

13) into the body by hand, then tighten the seat

(#29, Fig. 12) with Reliable P/N 6881603000 Seat

Wrench for 2” (50mm), 2½” (65mm), 76mm and

3” (80mm) valve sizes, Reliable P/N 6881604000

Seat Wrench for 4” (100mm) valve size, Reliable

P/N 688106000 Seat Wrench for 6” (150mm and

165mm valve sizes or Reliable P/N 6881608000

Seat Wrench for 8” (200mm) valve size until it bottoms out on the mounting ring (#5, Fig. 13).

Verify that the seat-clapper-mounting ring subassembly is in the fully down position between the

tabs of the body, and check to see that the lever

(#15, Fig. 13) lines up with the push rod (#25, Fig.

13). Loosen and reassemble if necessary. Reassemble the handhold cover (#7, Fig. 13) and set up the Model DDX Deluge Valve as per the section “Resetting Model DDX Deluge Valve Single

Interlock Preaction Systems”.

For Valve Sizes: 4” (100mm), 165mm, 6”

(150mm) with Drop-In Seat Confi guration only, Refer to Fig. 14:

It is likely that the lower seat o-ring (#11, Fig. 14) has remained at the bottom of the Deluge Valve body’s bore. Discard this o-ring and clean the bore. Lubricate the bore with o-ring grease and place the lower o-ring on the step at the bottom of the bore, verifying that it is in full contact with the bore. Lubricate the bottom step and upper oring (#11, Fig. 14) of the refurbished clapper-seat subassembly. Insert the clapper-seat sub assembly into the hand hole opening, lever (#7, Fig.

14) first and rotating the clapper-seat subassembly until the lever faces the outlet of the deluge valve. Next rotate the clapper-seat subassembly

90 degrees about the center axis of the valve until the bottom of the clapper-seat sub assembly faces the pushrod (#20, Fig. 14). Then rotate the clapper-seat subassembly 90 degrees counterclockwise so that the clapper (#3, Fig. 14) is facing the outlet of the deluge valve and the lever

(#7, Fig. 14) is facing the pushrod (#20, Fig. 14).

Once the clapper seat subassembly is in this position simply slide the assembly into the bore of the valve, making sure it is straight to avoid binding of the seat in the bore. Slightly twisting the assembly will assist in getting the clapperseat subassembly properly seated. Once it is verified that the clapper-seat sub assembly is in the fully down position and the lever (#7, Fig.

14) is aligned with the pushrod (#20, Fig. 14), clean and lubricate the two locking pins (#17,

(not shown) Fig. 14) with o-ring lubricant. Slide the two locking pins into the deluge valve body to lock the seat in place. Slightly twisting and pressing down on the clapper-seat subassembly will help the pins to slide in more easily. Then reinstall the 3/8” NPT pipe plugs (#19, (not shown)

Fig. 14). Reassemble the hand hole cover (#4,

Fig. 14) and set up the Model DDX Deluge Valve as per the section “Resetting Model DDX Deluge

Valve Single Interlock Preaction Systems”.

7. Leakage out of the push rod chamber vent hole:

A small bleed hole is located on the underside of the push rod chamber (see Fig. 13 or Fig. 14). If there is air or water leakage coming out of this hole, do the following: a) Shut down the valve controlling water supply to the Deluge Valve. Relieve the inlet pressure by opening the 1¼” main drain valve on the 2”

(50mm), 2½” (65mm), 76mm and 3” (80mm) valve sizes or the 2” main drain valve on the 4”

37.

(100mm), 165mm, 6” (150mm) and 8” (200mm) valve sizes, valve B (Fig. 15). Close the valve

A (Fig. 15) that supplies water to the push rod chamber, and open the Model B Manual Emergency Station, valve D (Fig. 15).

b) Remove the trim at the unions nearest to the push rod chamber cover (#3, Fig. 13 or #8 Fig. 14).

c) Take the push rod chamber cover (#3, Fig. 13 or #8, Fig. 14) off by removing the six retaining screws (#26, Fig. 13 or #29, Fig. 14).

CONDITION ONE (Water coming out of the bleed hole):

Water coming out of the bleed hole is caused by a leaking diaphragm (#18, Fig. 13 or #34, Fig. 14). Visually inspect the push rod chamber cover (#3, Fig. 13 or #8,

Fig. 14) and piston (#17, Fig. 13 or #18, Fig. 14) to determine what could have damaged the diaphragm and correct. Install a new diaphragm. NOTE: The diaphragm has two different surfaces; it is not bi-directional. It will fail if installed backwards! Roll the diaphragm so that the smooth surface (the pressure side) conforms to the inside of the push rod chamber cover and reassemble the six retaining screws (#26, Fig. 13 or #29, Fig. 14) with an installation torque of 15 foot-pounds. Set up the Model

DDX Deluge Valve as per the section “Resetting Model

DDX Deluge Valve Single Interlock Preaction Systems”.

CONDITION TWO (System Air coming out of the bleed hole):

System air coming out of the bleed hole is caused by a defective O-ring assembled to the push rod guide (#11,

Fig. 13 or #9, Fig. 14). Remove the piston-push rod subassembly, push rod spring (#34, Fig. 13 or #32, Fig. 14), and push rod guide (#11, Fig. 13 or #21, Fig. 14). Verify by hand turning, that the push rod cannot be unscrewed from the piston. Replace all O-rings and the push rod guide (#21, #22 & #11, Fig. 13 or #9, #12 & #21, Fig. 14).

The correct installation torque for the pushrod guide is 35 inch-pounds. CAUTION: Do not over tighten the push rod guide. Reassemble the components that were initially removed. Re-install the diaphragm (#18, Fig. 13 or

#34, Fig. 14) if it appears to be in good shape, otherwise, replace it also. NOTE: The diaphragm has two different surfaces; it is not bi-directional. It will fail if installed backwards! Roll the diaphragm so that the smooth surface

(the pressure side) conforms to the inside of the push rod chamber cover and reassemble the six retaining screws

(#26, Fig. 13 or #29, Fig. 14) with an installation torque of 15 foot-pounds. Set up the Model DDX Deluge Valve as per the section “Resetting Model DDX Deluge Valve

Single Interlock Preaction Systems”.
