Solenoid valves VZWF, force pilot operated
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
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.
