Wastewater combined air release valve

Request product
HAWLE_Air release Valves for waste water

Diameter range DN 80

Pressure rating PN 16


  • The combined air release valve comprises a PE chamber with a 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
