Compact Wastewater Air Valve
T-T's compact double orifice air valves efficiently release gas to prevent pressure build-up, control the bleed of gas to maintain system stability and allow the gradual ingress of gas to prevent vacuum in the pipe system.
Their lightweight ductile iron design and corrosion-resistant epoxy coating are suitable for wastewater and sewage applications, also available in stainless steel.
