V4055A,B,D,E ON-OFF FLUID POWER GAS VALVE ACTUATOR

60-2309—1

IMPORTANT

1. All wiring must comply with all applicable electrical

codes, ordinances, and regulations. All wiring must

be NEC Class 1.

2. Voltage and frequency of the power supply connected

to this control must agree with those marked on the

device.

3. Loads connected to the Auxiliary Switch and/or Proof-

of-Closure Switch, if used, must not exceed the rat-

ings given in the Specifications section.

Install Valve

The actuator is mounted directly on the valve bonnet after the

valve is installed in the gas supply line. Refer to the instructions

packed with the gas valve for installation details. When

installing the gas valve, make sure:

1. Sufficient clearance is left to install and service the actuator.

2. Ambient temperatures at the valve location do not

exceed actuator ratings. See Specifications section.

3. Position of the valve permits hookup to the damper if one

is controlled.

Install Accessory Switches (If
Needed)

An spdt switch can be installed to operate an auxiliary load up

to 1/2 hp (0.37 kW). See Table 5. The switch can be adjusted

to operate at any point in the valve stroke.

A Proof-of-Closure Switch can also be installed with a V5055/

V5097C or E Valve (with double seal) on any V4055 Actuator

to provide a valve seal overtravel interlock. The spdt

Proof-of-Closure Switch is installed to make or break a circuit

when the valve is in the closed position. The switch is not

adjustable.

NOTE: Mark the actuator or valve to indicate any changes

made.

To install the switches:

1. Remove the actuator faceplate (two screws).

2. Remove the silver-colored barrier to expose the actuator

stem.

3. Insert the Auxiliary Switch in the position indicated in Fig.

2. Fasten with two screws through the actuator base.

4. Insert the Proof-of-Closure Switch in the position shown

in Fig. 2. The switch mounts against the side of the

actuator housing. The mounting holes are spaced to

assure mounting the switch in the correct position.

Fasten with two screws through the actuator base. (The

Proof-of-Closure Switch is not adjustable.)

5. If only one switch is used, install the narrow barrier

included with the switch in the unused space.

6. Mount the actuator before making wiring connections

and adjustments to the Auxiliary Switch.

Mount Actuator on Valve

1. Check the final position of the valve body to be sure that

the actuator is in the proper position when mounted on

the valve. This is especially important when the actuator

is used to drive a damper.

2. If two smaller sized valves are mounted very closely

together, as in an Industrial Risk Insurers approved type

of valve train, it may be necessary to mount the

actuators off center to provide adequate clearance.

3. Slip the bottom collar of the actuator over the

valve bonnet assembly. Rotate the actuator to the

desired position and use a 5/32 in. Allen wrench to

securely tighten the two setscrews to 50 to 60 lb-in.

(5.7 to 6.8 N•m).

4. Connect the damper linkage, if used. Refer to the

instructions packed with the damper arm.

Mount and Adjust 7616BR
Damper Crank Arm (If Used)

IMPORTANT

When a damper crank arm is used with a NEMA 4

actuator that is exposed to ice or sleet, a suitable

shield must be installed to prevent ice or sleet

buildup.

Follow installation and adjustment directions included with

damper crank arm. Maximum pushrod travel is 2-5/16 in.

(59 mm) through a stroke of 52 degrees. See Fig. 3.
