7.1
Information for the correct
installation position
Depending on the valve body, the installation position of the dia-
phragm valve is different.
Installation for leakage detection:
One of the relief bores in the diaphragm socket for moni-
toring leakages must be at the lowest position.
7.1.1
Installation position of 2/2-way valve
body
Installation position: any, preferably actuator facing up.
Ensuring self-draining:
It is the responsibility of the installer and the operator to
ensure self-draining.
Self-draining must be considered during the installation:
1. Angle of inclination of the pipeline:
• The angle of inclination should correspond to the angle of
inclination of the pipeline. For the pipeline, we recommend the
inclination angles according to the valid ASME BPE.
2. Self-draining angle for valve body:
• The self-draining angle (α) depends on the valve body size (dia-
phragm size) and the inner diameter of the port connection (DN).
• The self-draining angle is specified as a value on forged steel
valve bodies (VS) and tube valve bodies (VP) (see "Fig. 7" and
"Fig. 9").

Installation
• The marking on the port connection of valve bodies serves as
an orientation aid. The marking must point upwards.
• The actual self-draining angle must be set with a suitable
measuring tool.
• For valve bodies without angle information, you can find the
self-draining angle on the Internet:
