Flow Control - Air Release Valve

ARV-034-A – Automatic Air Release Valve
DN25 with DN20 Base

The ARV-034-A is a automatic air release valve. Its function 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 trapped air 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. This maintains a constant air gap between the sealing mechanism and the medium.
