Air valve for sewage water and potable water

The air valve with unique roll-on membrane is perfectly suitable to release major amounts of air under operating pressure. The valve seat is not in contact with the medium. The air valve operates continuously from 0 to 16 bar, perfectly sealing even when unpressurized. The sealing principle with roll-on membrane has a shock-absorbing effect.

The air valve is provided with a flushing connection. By connecting a flushing line, dirt can be flushed out of of the air valve easily and quickly. In case of major dirt, the interiors have to be dismantled, cleaned and re-installed.

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

Max. air release capacity: 440 Nm³/h
Operating range: infinitely variable from 0 - 16 bar
Lower outlet: flange, flange mating dimensions

Following special functions on request
- Only air release
- Only air intake
- Air release stop: for lines purged with compressed air (note: reduced air release capacity)

For further information please refer to "Technical description" at the end of the chapter.
