Operation

Rotating the operator (handwheel or chainwheel) clockwise closes the valve. To actuate the valve from
full open to full closed (or vice-versa), the Size 6 requires 13 revolutions, the Size 12 requires 19
revolutions and the Size 16 requires 33 revolutions of the operator.

Required Tools

This actuator is assembled using only SAE fasteners. To service this unit, you should have a full set of
combination wrenches, Allen wrenches, a flat tipped screwdriver, a 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 is disassembled, apply a liberal amount of lubricant to the gear sector,
bearings and worm gear (size 6 and Size 12) or the rack (Size 16) using one of these lubricants:
- Keystone Zeniplex-1 (recommended)
- Amoco Amolith Grease #1-EP (alternate)
- Amsoil GHD (alternate)
- Mobil Mobilux EP 1 (alternate)
- Petro-Canada Vultrex MPG EP 1 (alternate)
- Shell Alvania EP 1 (alternate)
- Texaco Multifak EP 1 (alternate)
