assembly of actuator and diaphragm
Caution!
danger of injury due to movable parts in the actuator.
▶ When applying or removing the pilot pressure on the actuator
keep members and other objects away from the actuator openings.
→
Insert the diaphragm into the T-guide of the pressure pieces
Make sure that the four spacing sleeves are installed
(RV70 only).
For easier assembly of the pressure pieces the actuator
spindles should be in the lower position (Close) (CFA, NC:
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
recesses of the pressure pieces
→
Tighten the setscrews on the pressure pieces
→
Close the covers (for RV50 with PP cover: muffler and screw)
→
Move the actuator to the upper actuator position (CFA, NC: by
applying pilot pressure; CFB, NO: by removing the pilot pressure).
→
Put the actuator / diaphragm on the body with correct alignment
(so that the markings made previously align).
→
Tighten the diagonally opposed body screws / nuts until there
is visible, uniform mechanical contact between the valve body,
diaphragm and actuator 12
