HaVent® aeration and ventilation set with manhole pipe made of PE-HD
Product news
Common
The HaVent® (BEG) aeration and ventilation set consists of a shaft with shut-off device and an aeration and ventilation valve. Thanks to its compact design, the BEG replaces complex, high-maintenance shaft structures. All maintenance work can be carried out from the surface. This avoids the dangers that arise when accessing shafts.
The HaVent® air release valve (BEV) with its unique rolling diaphragm technology is ideally suited for venting large volumes of air when filling and emptying the pipeline, as well as for venting large volumes of air under operating pressure. The BEV operates continuously from 0 - 16 bar and seals perfectly even when depressurised.
