Air valve set for potable water

This air valve set consists of a shaft with a shut-off facility and an air valve. Due to its compact design, the AVS replaces complex and high-maintenance manhole constructions. All maintenance and repair work can be carried out from the terrain surface, thus avoiding the dangers possibly related with the access of manholes. We recommend the installation of a seepage hose (Ord. No. 490-04) in combination with seepable backfilling.

The air valve featuring the patented roll-on diaphragm technology is perfectly suitable both for taking in and releasing high amounts of air during fi lling or draining of pipelines and for releasing major amounts of air under operating pressure. The AV operates continuously from 0 to 16 bar, perfectly sealing even in unpressurized condition. The sealing principle with a roll-on diaphragm helps to absorb pressure surges. Due to the high air intake capacity, the AV is additionally provided with effective vacuum protection.

The shut-off unit included in the BEG can be opened and closed from the road surface with the help of a valve key according to DIN 3223.

Max. air release capacity: 700 m3/h
Max. release cross section: 1.500 mm2
Cross section of in-service ventilation: max. 200 mm2
Working range: 0 -16 bar

Special functions on request:
• With closing aid for more active closing (e.g., for well pipes between the pump and water preparation, high-level tank or pure water container, well mouth, for venting the pressure line)
• Air release
• flood protection
