INSTALLATION

9.1

Safety instructions for installation

WARNING!
Risk of injury due to improper assembly.
▶ Installation may be carried out by trained technicians only and with the appropriate tools.
▶ Secure the system to prevent 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 a heavy device.
A heavy device can fall down during transport or during installation and cause injuries.
▶ Secure heavy equipment to keep it from tipping or falling over.
▶ Transport, install and remove heavy device with the aid of a second person only.
▶ Use suitable tools.

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 monitoring leakages must be at the lowest
position.
9.2.1 Installation position for 2-way valve body
Installation position: any, preferably actuator facing up.
Ensuring self-drainage:
The installer and the operator are responsible for ensuring self-drainage.
Self-draining must be considered during the installation:
• Inclination angle of the pipeline.
To ensure that the pipeline is self-draining, we recommend the inclination angles according to the valid
ASME BPE.
• Self-draining angle for valve body:
The self-draining angle (α) depends on the valve body size (diaphragm 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. 15" on page 28 and "Fig. 16" on page 28).
