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. 20: Disassembly / assembly the diaphragm" on

Tighten the diagonally opposed body screws / nuts until there
is visible, uniform mechanical contact between the valve body,
diaphragm and actuator.
