Air Release Valves

SKAA – Anti-Shock Sewage Combination Air Release Valve

Non-clogging design for sewage and effluent service.

Product Description

The SKAA is specifically engineered for sewage and effluent service. The non-clog ball float resists fouling from fibres, greases and solids present in wastewater. The anti-shock mechanism prevents pressure surges when air is suddenly expelled. The smooth internal profile and ball float design eliminate the crevices that harbour blockages in standard air valves. Suitable for municipal wastewater, pumped sewage rising mains and industrial effluent systems.
