GX 3-Way Valve and Actuator

August 2011

CAUTION

Be careful when inserting the plug/stem assembly into the cage. Lower the plug into the cage slowly as this will seat the

seal ring to the plug. Make sure the seal ring (key 37) or backup ring (key 38) does not become disengaged from the cage

groove.

7. To insert the plug/stem assembly (key 3) into the cage (key 2), apply a general purpose silicone-based lubricant.

Slowly insert the plug/stem assembly into the cage.

CAUTION

If the packing is to be reused and was not removed from the bonnet, perform the following step carefully to avoid

damaging the packing with the stem threads.

8. Insert the bonnet and actuator yoke onto the valve body by completing the assembly according to steps 14 to 27 of

the section Replacing Packing, omitting step 17 if new packing is not being installed.
