A.R.I. Flow Control Accessories products

The D-020 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.

The D-020 SB is a complete product package that combines the reliable and efficient properties of the A.R.I. D-020 combination air valve for wastewater with the added feature of a sub-surface valve that can be buried below ground. A specially designed horizontal sliding disc valve - situated at the base of the D-020 SB assembly - allows for the air valve disconnection and maintenance from ground level. This shut-off valve is equipped with a safety mechanism enabling disconnection and removal of the D-020 air valve from its sub-surface housing, even when the system is under pressure. Since service and maintenance operations of the unit are performed entirely from the surface, there is no need for safety considerations associated with confined space entry.
