Install a PTFE diaphragm
1. Verify that the O-ring is installed on the diaphragm shoulder seal.
2. With the air source off or disconnected, thread the diaphragm onto the actuator shaft
and turn it clockwise until it stops. This ensures that the diaphragm is fully threaded
onto the actuator.
DO NOT FORCE! Finger-tight is sufficient.
3. Insert the actuator and diaphragm assembly into the valve body.
NOTE! Do not install gaskets between the valve body and the actuator.
Verify that the actuator is in the closed position (the indicator at the top of the
actuator is flush with the actuator).
Indicator ush = Closed position Indicator out = Open position
