Screw Single Air Vent Valve for small size DN20-DN50
air valves in pipeline systems serve two primary functions. The first is the release of accumulated air that comes out of solution within a pressurized pipeline. This air will result in bubble formation, which will gather at localized high points along the pipeline profile. This air accumulation will occur when the bubble`s buoyancy is greater than the energy to convey the bubble with the liquid. The A.R.I. Air Valve used to release this free air is known as an Air Release Valve.
