Water Air & Vacuum Valves ARIARI Air Valves Spare Parts Ordering
A.R.I. air valves for wastewater are specially designed to operate with liquids containing solid particles such as wastewater and effluents and liquids which can cause chemical build-up. The valve builds an air gap which separates the liquid from the sealing mechanism, ensuring optimum valve operation.
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. Installations are intended for: Pump stations for sewage, wastewater & water treatment plants, Wastewater and effluent water transmission lines

The D-025 Series are reduced bore compact combination air valves installed on a wastewater transmission system to increase pipeline efficiency and reduce energy requirements by improving the hydraulic operation of the system. A continuous air gap in the valve body separates the wastewater from the sealing mechanism. Body and Cover Polymeric materials



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. D-025 Sewage Air Valves ARI by Aquestia Brochure.

The D-025L Series are reduced bore compact combination air valves installed on a wastewater transmission system to increase pipeline efficiency and reduce energy requirements by improving the hydraulic operation of the system. A continuous air gap in the valve body separates the wastewater from the sealing mechanism.

Long D-025L model applications:
- High Pressure PN16 240PSI.
- Small Suspended Solids
- Builds an air gap that separates the liquids with suspended particles from the sealing mechanism.
- Less water dripping for small clean rooms etc.
