5.3.1. Assembly

For assembly of the valve, proceed as described following:
→ Move actuator in the "open" position.
→ Place the actuator properly on the valve body. Take care for correct orientation of the diaphragm weir and
valve body weir.
→ Place bolts and screw in hand-tight.
→ Close pneumatic operated actuator or respectively close manual actuator by 80%.
→ Fasten bolts or nuts crosswise with following tightening torque:
Diaphragm size
(MA) EPDM, FPM, NBR
MA 8 0,5 Nm
MA 10 1,5 Nm
MA 25
MA 40
MA 50 14 Nm
MA 65 50 Nm
MA 80 50 Nm
MA 100 40 Nm
MA 125 50 Nm
MA 150 50 Nm
MA 200 40 Nm
MA 250 40 Nm
MA 300 40 Nm
→ Check the valve for function and tightness.
Take care for simultaneous compression of the diaphragm – about 10%, depending on diaphragm
material and version. Especially PTFE-diaphragms have a setting behavior. Check the valve after the
first thermal load latest and re-tighten the bolts if necessary.
