Air relief valve ARL

stainless steelbronzeflange

While the system is flowing under pressure, air release valves continually and automatically exhaust the small quantities of air that would otherwise be collected at system high points. This ensures the system remain free of trapped air (and sewage gases) thereby increasing system efficiency and reducing pumping costs. Benefits Pressure relief function (exceeding atmospheric pressure) Liquid overflow protection Relief of small air pockets from pipeline Increase of pump efficiency Less system energy Maintenance free
