FIVC Automatic Air Vent is designed as a single-, double-, or/and a triple action valve
with an orifice to release volumes of air when the
line is under pressure, to discharge volumes of air during the
filling and/or to admit air into the system during system
drainage, valve or pump shut-off or at water column separation, all depending of valve selection.
Benefits of using the FIVC Air Vent are its contribution
for an efficient flow since air pockets lead to restrictions of
the flow, hence unnecessary head loss and sometimes also
flow stop. Air pockets do also lead to water hammer that
can damage equipment including other valves in the pipeline.
