Solenoid valves VZWF, force pilot operated, NPT
Key features and overview
Function
Normally closed solenoid valve
with diaphragm and forced lifting.
When the solenoid is energised,
the differential pressure from the
secondary side of the diaphragm is
reduced via the servo hole. The
effective differential pressure lifts

-M- Flow rate Kv

the diaphragm away from the valve
seat. If there is no differential
pressure, the diaphragm is lifted
directly by the solenoid. The valve
opens and closes without a differ
ential pressure between the inlet
and outlet.
Suitable for closed applications
such as cooling or filling systems
Vacuum
Liquid gas
Bottling systems
Diaphragm valves
Forced lifting of the valve
diaphragm
2/2-way valve, normally closed
Choice of sealing materials for
different fields of applications
Medium pressure 0 bar or higher
-H- Note
The valves are suitable for vacuum
with Pabs 100 mbar. Please
ensure the direction of flow corres
ponds to the direction of the arrow.
