Wastewater Air Valve

Our three function double Wastewater Air Valves control the ingress, discharge and bleed of accumulated gasses into pipelines to protect them from damaging vacuums and water hammer caused by pressure fluctuations; maintaining a stable system for more efficient flow.

They have a robust and low maintenance design, constructed from strong and lightweight ductile iron.

See our Working with Air Valves document for more information.
