Air valve HaVent® for potable water PN 16

The air valve with unique roll-on membrane is perfectly suitable to release major amounts of air under operating pressure. The sealing principle with roll-on membrane has a shock-absorbing effect.

Please note: air valves contain compressed air. Prior to any maintenance work the air valve shall be put out of operation and depressurized!

The air valve featuring the patented roll-on diaphragm technology is perfectly suitable both for taking in and releasing high amounts of air during fi lling or draining of pipelines and for releasing major amounts of air under operating pressure. The AV operates continuously from 0 to 16 bar, perfectly sealing even in unpressurized condition. The sealing principle with a roll-on diaphragm helps to absorb pressure surges. Due to the high air intake capacity, the AV is additionally provided with effective vacuum protection.
