Cast iron Single Air Release Valve ,release air and water
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.
