McAlpine Ventapipe 50 Air Admittance Valve for 3" and 4" pipe
The McAlpine Ventapipe 50 Air Admittance Valve is designed with dual fit synthetic rubber finger seal outlet for 3"/75mm or 4"/110mm soil pipe.
The valve diaphragm lifts and allows 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.
