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
