other body designs
→
Connect body to pipeline.
6.3.2 installing the actuator (welded body)
→
Move the actuator to the upper actuator position (CFA, NC: by
applying pilot pressure; CFB, NC: by removing the pilot pressure).
→
Put the actuator / diaphragm on the body with correct alignment
(so that the markings made previously align). In the case of RV110
the four spacer sleeves must be inserted in the designated body
holes (see "Fig. 7: Spacer sleeve").
→
Tighten the diagonally opposed body screws / nuts until there
is visible, uniform mechanical contact between the valve body,
diaphragm and actuator.
→
Switch the diaphragm valve twice.
