Description

The manual operated G-Series actuator is designed to operate a PEF 100% Port Eccentric plug valve.

External adjustable stops limit actuator stroke for both the open and closed valve positions. This

actuator is available in two sizes: Size 6 and Size 12. See Figure 1 to identify which unit you have.

Figure 1— G-Series Actuator Identification

Operation

Rotating the operator (handwheel, chainwheel or 2" nut) clockwise closes the valve. Counterclockwise

rotation of the operator opens the valve. To actuate the valve from full open to full closed (or vice-

versa), the Size 6 requires 13 revolutions and the Size 12 requires 19 revolutions of the operator.

Tools Required

This actuator is assembled using metric fasteners. To service this unit, you should have a full set of

combination or ratchet wrenches, Allen wrenches, flat tipped screwdrivers, a 1/4" pin punch and a dead

blow hammer.

Lubrication

The G-Series actuator has been lubricated at the factory and requires no routine maintenance

lubrication. If the actuator requires disassembly, see the ACTUATOR DISASSEMBLY AND

ASSEMBLY section in this instruction for disassembly, lubrication and assembly procedures.
