Functional description
The DUNGS vent gas solenoid valve
is an automatic shut-off valve operated
with auxiliary power. The electro-
magnetic drive closes against the force
of the pressure spring. If the auxiliary
power is interrupted (operating voltage),
the pressure spring opens the
valve within 1 second.
The closed position of the valve can
be monitored by a mountable closed
position signal contact.
