Flow Control - Air Release Valve

ARV-034-KA – Combination Air Release Valve DN25 with DN20 Base

The ARV-034-KA incorporates a kinetic and an automatic air release valve in one single valve body. 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:

  • Kinetic Function: Vents air from the pipes as they fill. When the water reaches the valve, the float rises, closing the valve.
  • Automatic Function: Purges the pipeline of air during operation by allowing the main float to drop, opening the smaller orifice which vents the air whilst still maintaining the main seal.
  • Pipeline collapsing is prevented by allowing the air to be drawn in through the valve.
