Cylinder Operated G-Series Actuator
Disassembling Actuator
13. Remove the screws or nuts fastening the cylinder assembly to the housing and carefully remove
the cylinder assembly by sliding it away from the actuator until the rack rod clears the actuator
housing.
14. Remove the rack from the housing.
15. Remove the rack bearing (if noticeable wear to bearing) by prying it from the actuator housing.
16. Scribe corresponding lines on the valve and adapter to be used for alignment during actuator
reassembly.
This valve is a pressure vessel. Removing the bonnet bolts before relieving pipeline pressure
can result in personal injury or equipment damage. Always relieve pipeline pressure before
removing the actuator.
17. Remove the screws fastening the adapter to the adaptor plate (2"- 4" valves) or to the valve
bonnet (5" - 16" valves).
18. Lift the rest of the actuator and the adapter off the valve.
19. Remove the screws fastening the adapter to the actuator housing, and separate the two parts.
Reassembling Actuator
Install new bearings and seals in the adapter and cover if necessary. See Figure 6 for proper
placement.
