D-025 | Combination Air Valve for Wastewater
150 psi – 2" – 4"
Description
The D-025 Combination Air Valve combines an air & vacuum orifice and an air release orifice in a single body. The valve is specially 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 while it is being emptied of liquid and releases accumulated air (gases) from the system while it is under pressure and operating. The valve’s unique design enables the separation of the liquid from the sealing mechanism and assures optimum working conditions.
Product Features
- Specially designed to operate with liquids carrying solid particles such as wastewater and effluents.
- Unique "air gap" design enables the separation of the liquid from the sealing mechanism and assures optimum working conditions.
- Combines the features of both an air & vacuum valve and an air release valve.
- Triple function:
- Air & vacuum component discharges large volumes of air during filling of the system.
- Air & vacuum component admits large volumes of air during drainage and at water column separation.
- The air release component releases entrapped air in pressurized systems.
- Available: 2"-4" with a threaded NPT connection.
- Available in flange sizes: 2"- 4" .
- These valves are manufactured with flanged ends to meet any requested standard.
