Design Features and Operating Concepts

Valves with electro-mechanical actuators

for quick opening or closing action

Normally closed shut-off valves are used in burner system fuel supply lines on industrial boilers, furnaces, ovens, kilns, and other heating processes.

All valves are designed to shut-off fuel automatically and instantly with an interruption in the electric power supplied through your safety circuit.

These valves are also used for the manual or

motorized opening or closing of pipe lines carrying gases and liquids commonly used in industrial processes. Normally closed valves cannot be opened until the interlocking safety control circuit is proven and resulting electrical power is supplied to the shut-off valve.

Motorized automatic valve actuators are used where remote access or unmanned applications are needed.

NOTE: Valve motors and solenoids are protected against thermal overload. If the valve duty cycle is exceeded, the motor and/or solenoid must be allowed to cool before the internal thermal protection will automatically reset.

Manual reset actuators require operating personnel to be physically present to actuate the valve from its at rest position.

Normally open vent valves are most often used as the bleed valve in a block-and-bleed pipe train, sometimes required by insurance authorities. They are designed to open a vent line automatically and instantly upon an interruption in the electric power supply through your safety control circuit.

These normally open valves are also used in protective atmosphere systems and other gaseous and fluid service requiring quick opening or by-pass purging action.

Like the normally closed versions, both automatic and manual reset actuators are available for remote access locations, or when operating personnel's physical presence is preferred.

All Maxon valves feature one-piece cast iron or

cast steel bodies with micro-lapped seats and discs.

Straight-through flow path minimizes pressure drop through full open swinging gate or rising stem (guillotine action) bodies.

Valve Body Design Details

Rising Stem

Valve Body

Assembly

To provide fuel shut-off in your process service lines, Maxon uses two different styles of valve bodies:

Rising stem (guillotine action) bodies are frequently used in normally closed and normally open gas valves. The microlapped, spring loaded guillotine disc gets a pressure assist from the flowing gases to seal against the downstream micro-lapped metal seat ring. The carefully machined seal surfaces and extremely close tolerances of the valve body operating mechanism promote positive closing action. Frequent cycling action constantly shears accumulated dirt or residue from the disc and seat to insure instantaneous and reliable sealing.

Seat

Normally Closed

Disc

The location of the port in the disc is the basic difference between normally open and normally closed valve bodies. Both valves function by the top assembly mechanism driving the stem and disc down into the valve body, opening (or closing) the flow path. Both valves trip to their rest position when their top assembly's compression spring is released to pull the stem and connected disc up out of the body.

Normally Open Disc

Swinging Gate

Valve Body

Assembly

Disc

Carrier

Swinging gate bodies are frequently used as normally closed oil valves and for some special service gas applications.

This design provides the same seal capabilities, but in a slightly different operating mode. The hard faced micro-lapped seat nut is threaded into the one-piece valve body. The free-floating, hard faced, spring loaded circular disc swings across the seat. Line pressure also assists in sealing the disc to the downstream seat.

Here again, frequent use and cycles actually helps to keep your valve clean. Since the free-floating disc is swinging across the circular seat nut on the arc created by the disc carrier, the disc rotates slightly on every cycle. This provides a fresh, clean surface area for sealing off the flow lines.

Disc

Maxon valve bodies have special service trim options available to meet your particular fluid service requirements.

NOTE: Typically, pressure drop for gas flows should not exceed 10% of inlet pressure; however, for 2" and smaller valves, the drop should not exceed 5 PSIG, and for 2-1/2" and larger valves, must not exceed 2.5 PSIG.

Select valve size on basis of the lower of these parameters to avoid critical flow conditions.

Temperature Limits

All of these valves can handle fluid temperatures from -20°F (-28°C) to

+250°F (+121°C).

Ambient temperature limits vary. The valves on this page handle ambient temperatures from -20°F (-28°C) to +140°F (+60°C).

Operation

All electro-mechanical valves require a constant supply of electrical energy to their holding solenoids inside the top assembly actuators. Once the solenoid is energized, the 730NI and 760NI valves may be opened manually, or the 4730NI and 4760NI valves will automatically open. Any interruption of the electrical power to either of these valves causes an immediate trip of the valve to its normally closed position.

Features:

• Normally closed

• Electrically actuated

• Swinging gate body

• For shut-off service

Rising Stem Body/Trim Specifications

All Maxon Rising Stem Gate Valves carry a two-part trim identification (for example, Trim 1-1).

The first digit (a 1, 2, 3, 4 or 5 before the hyphen) identifies valve body and bonnet material as shown in

Table 1 below.

The second digit (a 1, 2, or 3 after the hyphen) identifies the specific internals used, as described in

Table 2 and identified in the sketches at right.

Internal trim -1 is normally suitable for clean fuel gases (for example, natural gas, propane, butane, clean atmosphere gases).

Internal trim -2 may be required for clean gases that require Viton seals or such gases as coke oven, refinery, town or off-gas, or #1 and #2 fuel oils.

Contact Maxon with specific fuel analysis for prices and/or availability.

Internal trim -3 is designed for more corrosive environments such as digester gas, sour natural gas and landfill gas. Contact Maxon with specific fuel analysis for prices and/or availability.

Normally closed and normally open threaded and flanged body versions are identical in material specifications.

Swinging Gate Body/Trim Specifications

Trim identification of Maxon Swinging Gate Shut-

Off Valves is two-part. The first digit before the hyphen is a number (1, 2, 3 or 4) identifying body material as shown in Table 1 below. The second digit after the hyphen identifies a trim utilizing the materials indicated in Table 2 below.

Standard sanctioned valves incorporating a cast iron body will normally be identified by trim 1-B or 1-D.

Sanctioned valves with steel body will normally be trim 2-D.

Component Identification

General Maintenance and Spare Parts

All safety devices should be tested at least monthly* and more often if deemed advisable.

Periodic testing for tightness of manual or motorized shut-off valve closure is equally essential.

*per NFPA 86-Appendix B-4 (1995)

These Maxon valves are designed for long troublefree service. Only items shown as suggested spare parts are considered field replaceable.

WARNING: Do not attempt field repair of valve

body, top assembly or motor drive unit. Any alterations void all warranties.

To determine suggested spare parts, identify series designation and serial number from the

valve’s nameplate. Refer to the illustration and legend below to identify suggested spare parts.

To order, specify:

1. Quantity

2. Assembly part number (if available)

3. Description

4. Electrical specification

5. Full nameplate information (from existing valve)

(shown for listed valves; others similar)

Nameplate designation does not reflect external accessory items or motor limit switch


Electrical Data for normally closed valves

General

All Maxon shut-off valves are electrically actuated from a power source, normally through the flame safeguard and/or safety control circuits.

Standard valve assemblies include an internal holding solenoid for 115 volt 50/60 hertz AC power.

(230 volt 50/60 hertz available upon request.)

The solenoid is energized whenever the valve is powered. The motor operator on automatic reset versions is powered only during the opening stroke.

Switch wiring diagram (reproduced below) is part of each valve assembly, summarizing electrical data and a full complement of optional signal switches.

Diagram shows valve in its normally closed (at rest) position. The indicated internal wiring is present only when the appropriate auxiliary switches are specified.

Automatic reset valves always include a VOS-1 SPDT valve open motor limit switch.

Good practice normally dictates that auxiliary switches in valves used for safety shut-off functions should be used for signal duty only, not to operate additional safety devices.

Signal switch designations:

VCS (Valve Closed Switch) is actuated at the end of the closing stroke. VCS-1 is SPDT; VCS-2 is 2

SPDT switches mounted side by side.

VOS (Valve Open Switch) is actuated at the end of the opening stroke. VOS-1 is SPDT; VOS-2 is 2


Switch amp ratings are shown on the schematic wiring diagram below.

DO NOT EXCEED rated amperage or total load shown.

Electrical Data for normally open valves

General

All Maxon normally open vent valves are electrically actuated from a power source, normally through the flame safeguard and/or safety control circuits.

Standard valve assemblies include an internal holding solenoid for 115 volt 50/60 hertz AC power.

Auxiliary Signal Switches

All Maxon NI Valves may be equipped with internally-mounted hermetically-sealed signal switch(es) to provide a proof-of-open or proof-of-closure valve position indication. Auxiliary signal switches indicate

Page 6225

when valve is open or closed and are normally connected electrically into your control panel lights or warning device circuit(s).

For normally closed valves:

VCS hermetically-sealed (Valve Closed Switch) is actuated when valve is fully shut. It is the upper, inverted snap-switch mounted on rear on switch bracket. VCS-1 is an SPDT (single-pole, doublethrow) switch. VCS-2 is (2) SPDT switches mounted side by side. All contacts are available for external circuitry.

VOS hermetically-sealed (Valve Open Switch) is actuated when valve reaches full-open. It is the lower snap-switch mounted on front of switch bracket. VOS-

1 is an SPDT switch. On automatic reset valves, its normally closed contact serves as a motor limit switch and is not available for external circuitry. On manual reset valves, normally closed contact is available for external circuitry. VOS-2 is (2) SPDT switches mounted side by side, used in lieu of VOS-1 for additional contacts.

Overhead Wheel & Chain Assembly

Overhead wheel and chain assembly allows operation of a manual reset valve in an otherwise inaccessible overhead location. A wheel is mounted onto the handle of the valve. The attached chain is weighted on one end and has a paddle handgrip on the other.

Once the valve is electrically energized, pulling down on the paddle will open normally closed versions or close normally open versions.

Maxon valve's free-handle design permits valve to trip to its rest position on any power interruption.

Wheel and chain assembly includes a length of chain to position the paddle handgrip slightly below pipe centerline. A standard length of 7 feet of chain is included with CP and larger valve sizes and 5 feet is included with all other valves. Extra chain (in one foot increments) may be specified to fit your specific location.

NEMA 4X Hardware Kit

General Information

Maxon “NI” Valves are available with hardware modifications which make it NEMA 4X compliant.

On automatic valves, these kits may be installed in the field. However, due to the linkage set-up of manual valves, this kit is only available as a factory installed accessory.

These kits consist of new corrosion resistant stainless steel external fasteners for all covers.

When ordering the factory installed NEMA 4X kit

for manual valves, the kit will include a new handle made of corrosion resistant stainless steel.

When these kits are factory installed, the nameplate will indicate NEMA 4X in the designation block as shown on Page 6218.
