VAG Spring-Loaded Air Valve

PN: 10/16/25 - DN: 300...800

Productgroup: Air Valves

Medium: Water

Spring-loaded air valve with very high venting capacity for rapid discharge of the medium present in the pipeline, for air release when filling the pipeline and during operation. Large cross-section for venting large amounts of air during fast switch-off procedures, rapid discharge or pipe bursts. Used in bottom outlets, barrages or dams, long-distance pipelines or downstream of large butterfly valves. The integrated friction damper reduces the speed of the closing movement and thus pressure surges.
