McAlpine Ventapipe 100 Air Admittance Valve with Solvent Weld Outlet for 4"/110mm soil pipe.
Valve diaphragm lifts, allowing air to be drawn into the system when it is subjected to negative pressure. On cessation of negative pressure the diaphragm returns to the closed position thereby preventing the escape of foul air into the building.
The valve is designed to open and close spontaneously when required thereby allowing a supply of air to adequately ventilate the system thus ensuring a smooth discharge.
A1 rated.
Air flow capacity of 19.4 l/s.
