• Before connecting the valve, ensure the pipelines are flush.
• The flow direction is optional.
8.2.1 installation position general
installation for self-drainage of the body
It is the responsibility of the installer and operator to
ensure self-drainage.
installation for leakage detection
One of the bores (in the actuator base) for monitoring
leakage must be at the lowest point.
8.2.2 installation position 2/2-way valve
type 2103
• The piston-controlled diaphragm valve can be installed in any
installation position, preferably with the actuator face up.
To ensure self-drainage:
→
Install body inclined by an angle α = 10° to 40° to the horizontal.
→
Observe an inclination angle of 1° – 5° to the line axis.
Forged and cast body: Mark on the body must point upwards
(12 o’clock position, see “Fig. 34”).
→
One of the bores (in the actuator base) for monitoring leakage
must be at the lowest point.
