MA, MF, MP-541x, and MP-55xx actuator positioning is independent of spring selected.

When using a Schneider Electric System 8000 controller or a 4 to 20 mA signal across a 500 Ohm resistor to get the proper voltage.

The black spring used on a normally open valves may eliminate the need for positive positioning actuators.

PNV-145-48 Blue spring is not part of this kit. It is only required for controllers limited to 10 volts or 20 mA maximums.

Used with signals limited to 10V such as 0 to 10 Vdc and 4 to 20 mA across a 500 Ohm resistor. Note a reduced control range.

The small unpainted spring may be added to provide addition close off.

The AV-601 linkage extension provides thermal insulation between the valve and actuator. It

is required for all heating valves with MF-5x13, MP-541x, MP-551x, MPR-561x, MPR-571x, and MPR-581x actuators. It is recommended for cooling valves with MF-5x13, MP-541x, MP-551x, MPR-561x, MPR-571x, and MPR-581x actuators. It is also used for higher ambient and fluid temperatures with MA-521x and MP-521x actuators. Re fer to AV-601 Linkage Extension Kit General Instructions, F-26280 for installation procedures.

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

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

Requirements • Tools:

– Screwdriver appropriate for slotted spring compression screw (not provided) – Linkage wrench (provided) or TOOL-20-1, packing and linkage wrench (not

provided)

• Installer must be a qualified, experienced technician

Caution:

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

• 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.

• The actuator must be above the center line of the valve. For steam applications mount

the actuators above the valve body at 45° from vertical.

Linkage Kit Installation

The AV-7600-1 linkage kit used on VB-7xxx series valve bodies requires no stem height setting.

Procedure

The linkage kit is assembled onto the VB-7xxx valve body with the stem in the up position.

1. Select the appropriate spring(s) as detailed in Figure-1.

2. Thread the hexagon coupler onto the valve stem all the way to the bottom of the stem thread, finger-tight (Figure-1). Pull the valve stem completely up.

Figure-2 Completing Linkage Kit Assembly to Valve.

Caution: The hexagon coupler must reach to within 1/16” (1.6 mm) of the smooth section of the stem to assure proper seating. Do not use the Spring Compression Screw to run the Hexagon Coupler down.

3. On normally closed valves (1-1/2” [40 mm] to 2” [50 mm] mandatory) slip the small unpainted booster spring over the stem.

4. Start the spring(s) compression screw one turn or more into the hexagon coupler.

5. Slip the spring over the coupler and the spring compression screw.

6. Place the retainer over the screw. Twist the retainer 45° to lock it in place.

7. Insert the linkage wrench (supplied with kit, also included on TOOL-20-1) through the spring coils about 3 coils from the bottom to hold hexagon coupler.

8. Hold the wrench from turning and tighten the spring compression screw. To establish proper linkage height, run the spring compression screw down until the screw end bottoms firmly on the stem top (

Figure-2).

9. Confirm the stem height setting (Figure-2):

• 2-7/32” (56 mm) maximum on stem up closed valves (VB-722x) or three-way valves

(VB-73xx).

10. Center the spring on top and bottom to assure smooth actuator operation. See Figure-3 for total assembly components required.

MAINTENANCE

The actuator linkage requires no maintenance. For linkage removal, insert wrench through springs and hold. Remove spring compression
