DeZurik G-SERIES Instruction

Lubrication

The G-Series Actuator has been lubricated at the factory and requires no routine lubrication. If the actuator is
disassembled, lubricate the worm gear and bearings and pack the gear sector teeth 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)

Adjustments

The closed position stop is a set screw located in the side of the actuator housing on the G12 unit, and
is located in the end of the extension cap on the G16 unit.
Adjust the set screw to position the valve in the closed position when the gear or rack contacts the set
screw. (Read the instruction sheet for the valve. Additional information on the proper closed position
may be included.)

Changing the Actuator Position

The possible actuator mounting positions are shown on the customer drawing. To change the mounting
position:
1. Shut off line pressure and close the valve.
2. Remove the actuator cover screws and the cover.
3. Remove the screws that fasten the actuator to the adaptor.
Note: These screws are located on the underside of the actuator.
4. Remove the actuator from the valve.
5. Remove the gear sector.
Note: Rotate it in the same direction and for the same number of degrees as the actuator will be
rotated, and reinstall the gear sector in the actuator. Be sure the key and keyway are engaged.
6. Place the actuator on the valve in the desired position, and install the screws that fasten the
actuator to the adaptor.
