Cylinder Operated G-Series Actuator

Disassembling Actuator

13. Remove the rack bearing (if noticeable wear to bearing) by driving the pin out of the rack

bearing and actuator housing.

14. Scribe corresponding lines on the valve and adapter to be used for alignment during actuator

reassembly.

This valve is a pressure vessel. On 4, 5, 6 and 10" (100, 125, 150 and 250mm) valves, the same

bolts hold both the actuator and the bonnet.

Removing the bolts on 4, 5, 6 and 10" (100, 125, 150 and 250mm) valves before relieving

pipeline pressure can result in personal injury or equipment damage.

Always relieve pipeline pressure before removing the actuator.

15. Remove the screws fastening the adapter to the valve; ensure the pipeline pressure is relieved

before removing these screws on 4, 5, 6 and 10" (100, 125, 150 and 250mm) valves.

16. Lift the rest of the actuator and the adapter off the valve.

17. 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 7 for proper

placement.
