The combined air release valve comprises a PE chamber with shut-off mechanism and an air release valve. #
Owing to its compact structure, the BEG replaces time-consuming, high-maintenance shaft structures.
All maintenance work can be carried out from the ground surface. This avoids the risks which arise when accessing chambers.
The air release valve with unique roll membrane technology is perfect for venting larger quantities of air under working pressure.
The sealing seat does not come into contact with the medium.
The BEV functions continuously between 0 and 16 bar and seals properly even when depressurized.
Water hammers are also diminished by the roll membrane and spring mechanism.
The BEV has two flush connections which are pulled up to the lower edge of the plastic cover.
Light soiling can be flushed out of the BEV by connecting a rinsing tube.
In the event of greater soiling, the BEV can be easily removed via a bayonet connection.
The shut-off unit is opened and closed with the extension shaft via a half-turn. A conventional valve key can be used to operate the extension shaft.
Max. air release capacity: 440 m³/hr operating range: Continuously from 0–16 bar lower outlet: Flange DN 80 with threaded bolt (70 mm) or BAIO® spigot DN 80 (dirt cover and locking ring required)
Special functions on request: - Only air release or only aeration - air release stop: For compressed-air-purged pipes
