Combination Air Valve For Sewage

Features

• The combination air valve combines an air & vacuum large orifice and an automatic small orifice in a single body
• The valve is specially designed to operate with liquids carrying solid particles such as sewage and effluent
• The combination air valves discharges air (gases) during the filling or charging of the system, admits air to the system while it is being emptied of liquid and discharges accumulated air (gases) from the system while it is under pressure and operating
• The valve’s unique design guarantees complete separation of the liquid from the sealing mechanism and provides optimum work conditions
• The valve’s unique design prevents any contract between sewage and the sealing mechanism by creating an air gap at the top of the valve. This air gap is guaranteed even under extreme conditions
