WARNING

When moving the actuator stem with diaphragm loading pressure use caution to keep hands and tools out of the actuator

stem travel path. Personal injury and/or property damage is possible if something is caught between the actuator stem and

other parts of the valve assembly.

Perform one of the following procedures as appropriate:

For a 3024C Air‐To‐Close Actuator with a Push‐Down‐to‐Close Valve:

a. Carefully place the actuator on the valve so that the yoke boss fits over the valve bonnet.

b. Screw the yoke lock nut onto the bonnet and tighten.

c. Lift the valve plug off the seat by the correct valve travel for the valve. This is stated on the nameplate or in table

d. Place the stem connector half (key 50) approximately halfway between the actuator and valve stems but

observing the F dimension in table 5 so that any positioner lever (if fitted) is horizontal at mid‐travel. Be sure that

the actuator and valve stem threads are engaging the threads of the stem connector by at least the distance of

one diameter of the stem.
