7 INSTALLING THE VALVE
WARNING!
Risk of injury due to improper assembly.
▶ Installation may be carried out by trained technicians only
with the appropriate tools.
▶ Secure the system against unintentional activation.
▶ After installation, ensure that the process is restarted in a
controlled manner. Observe the sequence.
1. Connect supply voltage.
2. Pressurise the device with medium.
CAUTION!
Risk of injury due to heavy device.
During transportation or installation work, the device may fall
down and cause injuries.
▶ Transport, install and remove heavy device with the aid of a
second person only.
▶ Use suitable tools.
ATTENTION!
The following must be heeded when installing the device in
the system.
The device and relief bore must be accessible for inspections
and maintenance work.
7.1 Installation position of the diaphragm
valves
Depending on the valve body, the installation position for the
diaphragm valve is different.
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.
Ensure self-draining:
→ 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.
