by removing the pilot pressure; CFB, NO: by applying the
pilot pressure).
→
Insert the pressure pieces into the actuator
the actuator spindles are fully inserted into the corresponding

note!
damage to diaphragm and valve malfunction.
▶ Turn the diaphragm and pressure pieces only far enough to align
