The actuator is installed directly on the V5055/V5097 body
after the valve is installed in the gas supply line. Refer to the
instructions packed with the V5055/V5097 Gas Valve for
installation details. When installing the valve, assure that:
1. Sufficient clearance is allowed for actuator installation
2. Ambient temperatures at the valve location do not
exceed actuator ratings.
3. Position of the valve permits damper hookup if one is
Install Accessory Switches (If Needed)
An spdt switch can be installed to operate an auxiliary load up
to 1/2 hp (0.37 kW). 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 V4062
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
NOTE: Mark the actuator or valve to indicate any changes
To install the switches, proceed as follows:
1. Remove the actuator faceplate (two screws).
2. Remove the silver-colored barrier to expose the
3. Insert the auxiliary switch in the position indicated in
Fig. 2. Fasten with two screws through the actuator
4. Insert the proof-of-closure switch in the position shown
in Fig. 2. The proof-of-closure switch mounts against
the side of the actuator housing. The mounting holes
are spaced to allow mounting the switch only in the
correct position. Fasten with two screws through the
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
Check the final position of the V5055/V5097 Valve body to
be sure that the actuator will be in the proper position when
mounted on the valve. This is especially important when the
actuator is used to drive a damper.
If two smaller size valves are mounted very close together,
as in an Industrial Risk Insurers type valve train, it may be
necessary to mount the actuators off center to provide
Slip the bottom collar of the actuator over the valve bonnet
assembly. Rotate the actuator to the desired position and use
a 5/32-inch Allen wrench to securely tighten the two setscrews
(50 to 60 lb-in. [5.7 to 6.8 N•m]). Connect the damper linkage,
if used. Refer to the instructions packed with the damper
