Flow Control - Air Release Valve

ARV-4 – Air Release Valve for Waste Water & Fresh Water Systems

The ARV-4 incorporates a kinetic and an automatic air release valve in one single valve body. Its function in the waste water and fresh water system is to allow air to be expelled from the pipeline during filling, and air to be admitted into the pipeline during emptying.

Applications:

When the pipeline is being filled, trapped air is released through the large orifice of the kinetic valve. During emptying of the pipeline, the valve allows air to enter the pipeline through the large orifice. During normal operation the large orifice remains closed while the small orifice allows small amounts of entrapped air which has accumulated, to be released through the valve.

The valve mechanism is designed to absorb small changes in pressure which prevents the small orifice from continually opening, thus maintaining a constant air gap between the sealing mechanism and the water.
