Installing the valve
7.1
Installation position of the diaphragm
control valves
Depending on the valve body the installation position for the
diaphragm control valve will vary.
One of the relief bores in the diaphragm socket for moni-
toring leakages must be at the lowest position.
7.1.1
Installation position for 2-way body
Installation position: Arbitrary, ideally with actuator facing upwards.
Ensuring self-drainage:
→
Install the valve body at an angle α = 10°...55° inclined to the
horizontal.
On forged steel and cast valve bodies there is a mark for this
which must point upwards (12 o'clock position, see "Fig.
10").

→
Observe an inclination angle of 1°...5° for the pipeline.
The installer and the operator are responsible for ensuring
self-draining.
