V4062A,B,D HI-LO-OFF FLUID POWER GAS VALVE ACTUATOR

OPERATION

To function as intended, the V4062 must be connected to a
properly sized valve. Too large a valve will not properly control
the gas flow.
When the actuator is energized, it drives to the adjustable
low-fire position. Depending on the demand of the controller,
the valve remains at low-fire or moves to the high-fire position.
When the firing rate controller calls for no heat, the actuator
returns the valve to the low-fire position. When power to the
actuator is interrupted, the valve completely closes.
Fig. 4 shows the V4062 in a typical flame safeguard control
system.

SERVICE AND CHECKOUT

CAUTION
Equipment Damage Hazard.
Unskilled technicians can damage the equipment.
Only experienced, trained flame safeguard control
service technicians should service or replace this
control.
Service
The actuator is not field repairable, except for replacing the
auxiliary switch or valve-closed indication switch. See
Installation section for procedure. Do not disassemble the
valve actuator. If the actuator should fail to operate properly,
replace it.
Checkout
After the installation is complete, cycle the valve several times
with the manual fuel shutoff cock closed before testing the
system in actual operation.
