Close-Off Pressure Rating

Refer to Table-1 and Table-2 to make sure the valve and actuator are compatible with each other, and that the close-off rating is adequate for the application. Refer to Ta b le - 3 and Ta bl e -4 for listings of obsolete valves and their corresponding actuators that used the AV-430 valve linkage. Verify that the valve body differential pressure is in compliance with the limitations specified for the valves being used with MM-400/500 actuators. Refer to

Environmental Controls Valve Selection Guide, F-26094 for detail information.

Close-Off Pressures for 3-Way Valves are Determined as Follows: The value for SU is the “A” port close-off pressure, and is based on the pressure at “A” port minus the pressure at “B” port. The value for SD is the “B” port close-off pressure, and is based on the pressure at “B” port minus the pressure at “A” port.

Factory assemblies of valve and actuator combinations are available for several of the selections listed in

Ta bl e -1 and Ta bl e -2 . Consult the Pneumatic Products Catalog, F- 27383 or Environmental Controls Valve Selection Guide, F-26094 for availability. Actuator and valve combinations not available as factory assemblies must be purchased separately, along with the appropriate valve linkage kit.

INSTALLATION

Inspection Inspect the package for damage. If damaged, notify the appropriate carrier immediately. If

undamaged, open the package and inspect the device for any obvious damage. Return damaged products.

Requirements • Parts:

– See Ta bl e - 6 for parts selection for the AV-430 valve linkage.

• Tools (not provided):

– Appropriate wrenches for stem extensions, locknuts, packing nuts, and bracket nuts. – Appropriate screw driver for actuator mounting screws. – TOOL-37, 1-5/8" open-ended wrench with a maximum thickness of 3/16"

• Training:

– Installer must be a qualified, experienced technician.

Caution:

• Avoid locations where excessive moisture, corrosive fumes, or vibration are present. Do

not insulate above actuator mounting nut trapping moisture.

• Install all two-way valves so that they close against the flow. An arrow on the valve body

or a tag indicates the proper flow direction.

• Always install three-way mixing valves with two inlets and one outlet.

• Always install three-way diverting valves with one inlet and two outlets.

• Do not install the actuator below the center line of the valve. For steam applications only,

mount the actuator above the valve body at 45° from vertical.

• When selecting a location, allow sufficient room for accessories and for servicing the

actuator.

Mounting 1. Actuators can be mounted in any upright position above the center line of a valve body.

2. When selecting a location, allow sufficient room for accessories and for service of the product.

3. Maintain proper flow direction when installing all globe and radiator-type valves. Flow direction is indicated by an arrow on the valve body or by information on the attached tag.
