The D-025 Combination Air Valve combines an air & vacuum component and an air release component in a single body. The valve is specifically designed to operate with liquids carrying solid particles such as wastewater and effluents. The combination air valve discharges air (gases) during the filling or charging of the system, admits air into the system during drainage and at water column separation and releases accumulated air (gases) from the system while it is operating under pressure. The valve’s unique design enables the separation of the liquid from the sealing mechanism and assures optimum working conditions.
Features
Working pressure range: 0.7 - 150 psi.
Testing pressure: 250 psi.
Maximum intermittent temperature: 194° F.
The unique design of the valve prevents contact between the wastewater and the sealing mechanism by creating an air gap at the top of the valve.
