HI-LO-OFF Fluid Power  
Gas Valve Actuator  
PRODUCT DATA  
The standard model has an opening time of  
6 seconds at 60 Hz, or 32 seconds at 50 Hz. A fast-  
opening model is available, with timings of  
3 seconds at 60 Hz, or 16 seconds at 50 Hz.  
2
1
Maximum closing time is one second, which meets  
code, standard, insurer requirements.  
Damper shaft models are available with or without  
spring return; shaft extends out both sides and rides  
in Delrin bushings; used with standard damper crank  
arm (part no. 7616BR).  
Red OPEN indicator attached to the actuator stem  
shows when the valve is even slightly open; yellow  
SHUT indicator on the valve stem shows only when  
the gas valve is fully closed.  
Ambient temperature range is -40° to 150°F (-40° to  
6
5
6°C) for 60 Hz models; -10° to 158°F (23° to 70°C) for  
0 Hz and 50/60 Hz models.  
Models available with factory adjusted, field-  
adjustable, single-pole-double throw (spdt) auxiliary  
switch rated at 1/2 hp (0.37 kW). Auxiliary switch can  
be added in the field.  
APPLICATION  
Low-fire position is adjustable with adjusting wrench,  
part no. 135796 (included with the actuator).  
The V4062 Gas Valve Actuator in combination with a V5055  
or V5097 Gas Valve provides three-position control of the  
gas supply to commercial and industrial burners.  
Standard enclosure meets NEMA 1 (IP30) general  
purpose requirements.  
V4062/V5055C,E and V4062/V5097C,E combinations  
available with a proof-of-closure switch and double  
valve seal (valve seal overtravel interlock) to meet  
specific code/standard/insurer requirements.  
FEATURES  
When energized, the V4062 Actuator opens the V5055/  
V5097 Gas Valve to the low-fire position. The actuator  
opens the valve to the fully open position when the  
line voltage contacts are made.  
Model available to be used with series 60 floating  
type controller.  
Model available with adjustable maximum flow  
switch.  
When used with the V5055,V5097 or VE5000 Gas  
Valve, the combination is rated for final safety shutoff  
service.  
Although the V4062 can be used with all V5055 or  
V5097 Valve models, the V5055/V5097B with  
characterized guide is recommended for optimum  
control and low-fire repeatability

Ambient Operating Temperature Rating:  
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:  
-
-
40° to 150°F (-40° to 66°C) for 60 Hz models;  
10° to 158°F (-23° to 70°C) for 50 Hz and 50/60 Hz  
models.

. Ambient temperatures at the valve location do not  
exceed actuator ratings.  
. Position of the valve permits damper hookup if one is  
controlled.

Connect the power from the flame safeguard control to  
terminals 1 and 2 on the V4062 terminal strip, and connect  
the firing rate controller to terminals 3 and 4. Refer to Fig. 4  
for typical connection. Fig. 5 shows the wiring for connecting  
the Max Flow Limit Switch to the actuator. For other typical  
system hookups, refer to the instructions packed with the  
device used to control the valve.  
When all wiring connections are complete, replace the

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  
adequate clearance.

Because the cam rotates as the valve opens, scales are

These scales are not independent; the same setting applies

IMPORTANT:  
When using the V4062 with a V5055/V5097C or E

For most effective use of the V4062/V5055 or V4062/V5097,  
be sure to select a valve body size closely corresponding to  
burner capacity. An oversized valve might not allow the low-  
fire rate to be adjusted to the desired minimum setting.

V4062A,B,D HI-LO-OFF FLUID POWER GAS VALVE ACTUATOR  
Recommended Procedure  
Adjust Auxiliary Switch (If Used)  
To adjust the low-fire setting without energizing the actuator,  
proceed as follows:  
The auxiliary switch can be adjusted to operate at any point  
in the actuator stroke. After installing the switch in the  
actuator, turn the adjustment screw (Fig. 2) clockwise  
to cause the switch to operate earlier in the stroke or turn

. Loosen the setscrew on the low-fire cam using the  
special wrench (supplied taped to the inside of the  
actuator cover).  
NOTE: The proof-of-closure switch is not adjustable.

the burner being used.  
. Tighten the setscrew in the cam.  
Adjust Max Flow Limit Switch (Fig. 2)  
The Max Flow Limit Switch is adjustable throughout the  
actuator stroke. With the switch installed in the actuator, turn

the adjusting screw clockwise  
to cause the switch to  
operate earlier in the stroke (less flow) or counterclockwise  
to cause the switch to operate later in the stroke (more flow).  
Alternate Procedure  
To adjust the low-fire setting after the burner is in operation,  
use the following instructions:  
OPERATION  
1
2
. Remove the wiring compartment cover.  
. Check to be sure the low-fire adjustment is set at MAX  
to assure a safe lightoff. (Low-fire adjustment is preset  
at the factory in the MAX position.)  
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.  
3
. Disconnect the firing rate controller leadwire from  
terminal 4 on the actuator to keep the valve in the low-  
fire position (Fig. 4).  
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.

5
. Start the system and establish the main burner flame.  
. Loosen the setscrew in the cam (Fig. 5) with the  
special wrench. Keep the wrench seated in the  
setscrew. Rotate the cam slightly downward (by  
moving the wrench toward the actuator base) to open  
the bleed valve. The actuator will start to close.  
. When the valve reaches the desired low-fire position,  
quickly tighten the setscrew and remove the wrench. If  
the desired low-fire setting is missed, loosen the  
setscrew and rotate the cam in the opposite direction  
to the desired setpoint.  
. Shut down the burner, and then restart. Repeat several  
times to be sure the low-fire setting is suitable for  
correct burner lightoff. Readjust, if necessary.  
. Disconnect power and reconnect the controller  
leadwire removed in step 3.

The V4062A1156 Fluid Power Gas Valve Actuator was  
modified to provide modulation between high-and low-fire  
positions when used with a Series 60 controller, such as the  
W964 Aquatrol® System and two auxiliary relays.  
The V4062A1156 will not operate properly wired similarly to  
other V4062 models. See Fig. 7 for suggested wiring
