General terms
Installation has to be done in such a way that liquids can drain off
the valve housing. Vertical position is preferred.
Valves can be welded direct into the pipeline (valve insert
completely dismantable).
- After the installation, the set value must be adjusted by a pressure
gauge.
Adjustment:
turn right
=
pressure increase
turn left
=
pressure reduction
If required, the value can be corrected during production
by turning the adjusting screw at the spring cylinder.
Attention!
Observe Welding Instructions 8.2.
Conductive connection to the pipeline must be provided.
The integration into the operational potential equalization must be
guaranteed!
