Air valve set HaVent® for potable water PN 25

This air valve set consists of a shaft with a shut-off device and an air valve. Due to its compact design the air valve set replaces complex and high-maintenance manhole constructions. All maintenance work for this air valve set can be carried out from ground level, thus avoiding all the dangers possibly related with the entering of manholes. The installation of a drainage element (model no. 992SE) is recommended.

The air valve PN 25 is perfectly suitable for releasing greater amounts of air under operating pressure. The air valve operates continuously from 0.2 - 25 bar. Due to the high volume of venting capacity this ARV provide a reliable protection against vacuum demages.

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

Max. air release capacity: 770 m³/h
Release cross section: 1,500 mm²

Operating range: 0.2 – 25 bar

The air valve set (standpipe, operating pipe) can be shortened on site by 100 mm at the marked points to adapt it to changed height conditions
.

Following special functions on request:
- With closing aid (see "Technical description")
- Air release / air intake only
- Installation for ground water applications
- Installation for flood water applications
