Checking the usage
Intended use
Magnetic relief valve, open when de-energized, for
the monitoring of gas valves for tightness used in
conjunction with a visual discharge unit. For purging
excess or leakage gas.
This function is only guaranteed when used within the
specified limits – see page 7 (Technical data). Any
other use is considered as non-compliant.

Installation
CAUTION
Please observe the following to ensure that the
magnetic relief valve is not damaged during instal-
lation and operation:
– Important! The gas must be dry in all conditions
and must not contain condensate.
– Sealing material and dirt, e.g. thread cuttings,
must not be allowed to get into the valve hous-
ing.
– A filter must be installed upstream of every sys-
tem.
– Do not store or install the unit in the open air.
– Dropping the device can cause permanent
damage. In this event, replace the entire device
and associated modules before use.
– Do not clamp the unit in a vice. Only secure the
flange by holding the octagon with a suitable
spanner. Risk of external leakage.
– Solenoid valves with overtravel switch and visual
position indicator VAN..SR/SL: actuator cannot
be rotated.
– Cleaning work on the solenoid actuator may not
be performed using high pressure and/or chemi-
cal cleaning agents. This can cause moisture
to get into the solenoid actuator and may lead
to a dangerous failure.
Installation position: black solenoid actuator in the
vertical upright position or tilted up to the horizontal,
not upside down.
▷
The housing must not be in contact with masonry.
Minimum clearance 20 mm (0,78").
Note direction of flow.
