General
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 Systems, 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
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 pi2.
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
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
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).
Reliable Model DDX Deluge Valve with associated Single
Interlock Preaction Trims sizes 2” (50 mm), 2½” (65 mm), 76
mm, 3” (80 mm), 4” (100 mm), 165 mm, 6” (150 mm) and 8”
(200 mm) are rated for use at a minimum water supply pressure of 20 psi (1,4 bar) and a maximum water supply pressure of 250 psi (17,2 bar) for 2” (50mm), 2½” (65mm), 76mm,
3” (80mm) and 8” (200mm) valve sizes and 300 psi (20,7
bar) for 4” (100mm), 165mm and 6” (150mm) valve sizes.
Water supplied to the inlet of the valve and to the push rod
chamber must be maintained between 40˚F (4˚C) and 140˚F
(60˚C).
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.

Pressurizing Line Connection
System Design Considerations
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.
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.
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 fire pump settings, underground construction
work, or an improper venting of trapped air in the water
supply piping.
19.
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.
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-4410RC Releasing Control Panel requires 120 VAC. Batteries that
provide ninety hours of standby power are required for Factory Mutual Approved systems.

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-

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:
1. Install ½” nipple (#35, Fig. 3 or #37, Fig. 4) in the tapped
opening marked “TEST”. Note: If interference occurs
between the supply gauge and the control valve, the
1/4” plug (#52, Fig. 3 or #52, Fig. 4) in the opening
marked “SUPPLY” may be swapped with: the 1/4”
nipple (#33, Fig. 3), angle valve (#9, Fig. 3) and gauge
(#67, Fig. 3) for the 2” (50mm), 2-1/2” (65mm), 76mm
and 3” (80mm) valve sizes; 1/4” nipple (#32, Fig. 4),

and connect the balance of this trim line.
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
Valves uses eight tapped openings for trim connections.
Each opening and its function are indicated on Fig. 5 or Fig.

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

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

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.

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.
Note: The reset knob can be rotated only while pressure in
the pushrod chamber is vented to atmospheric conditions
(0 psig).

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).
Inspect and replace any portion of the detection system
and/or sprinkler system subjected to fire conditions.
Open valve A (Fig. 15) and allow water to fill the push rod
chamber. Close valve D (Fig. 15).
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).
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.
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.
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.
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.
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.
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.

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:
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:
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 Configuration
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
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 Configuration 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
36.
7.
(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”.
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 Configuration
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”.
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”
