986-00
Air valve for sewage water and potable water

The vent valve with unique rolling diaphragm technology is ideally suited for venting large volumes of air under operating pressure. The sealing seat does not come into contact with the medium. The BEV works continuously from
0 to 16 bar and seals perfectly even in a non-pressurized state. The sealing principle with rolling diaphragm has a pressure-shock-absorbing effect.

Max. venting capacity: 440 m³/h
Operating range: infinitely variable from 0 - 16 bar

Ventilation cross-section: 480 mm2
Bottom outlet: flange or female thread

Special functions on request:
- Vent only
- Ventilation only
- Vent stop: for compressed air-flushed pipes

Version Oxidizer see order no. 986-05,
can also be retrofitted with conversion kit Order No. 986 002 9952
