Description:
HaVent® Automatic and infinitely variable air valve for potable water for operating range: 0 - 250 PSI (PN16)
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.
The air valve operates continuously from 0 to 17,2 bar, perfectly tight even when unpressurized.
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 17,2 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 Air release valve is additionally provided with effective vacuum protection
- Very high air release and intake during operation infinitely variable from 0 to 250 psi (17,2 bar)
- Max. air release capacity: 250psi: 3,700 gal/m (500 cfm)
- Vacuum breaking function
- Corrosion resistant materials
- Ultraviolet resistance
- Ease of maintenance
- Virtually spill proof
