Trykk-vakum ventiler (Press-Vacum) 02-311-001

High velocity pressure vacuum valve prevents pressure and vacuum to build-up during loading,
discharge, transport and storage.

The High velocity pressure valves
is also capable of preventing the passage of flames in case of ignition or
fire outside the tank atmosphere.Separate pressure and vacuum valves are elegantly integrated in a single
housing. If the pressure in the tank falls below a pre-set level the vacuum valve opens and air isdrawn into
the tank through a flame trap. In the event of overpressure, the release valve opens. At the same time an
additional valve at the top of the housing ensures that venting is upwards at high velocity, to avoid
concentrations of gas on deck.
