Air Release Valve

Air release valves protect water and wastewater pipelines by venting trapped air during filling, releasing accumulated air under pressure, and admitting air during drain-down to prevent vacuum collapse. AFC Valves EU supplies a full range of combination, kinetic, and anti-shock air release valves for utilities, irrigation networks, sewage transmission mains, and pump stations across Europe. Our KAR series covers clean-water service from DN50 to DN300, while the SKAA, SKAR, and SKAS ranges are designed for sewage and effluent service with non-clogging internals. All valves are supplied with material certificates and are available in ductile iron with epoxy coating, with optional WRAS-approved seats for potable water duty.
