Help protect pipelines against excess pressure with a relief valve from Grainger. Choose from a wide range of pressure relief valves that can release pressurized fluid through an auxiliary exhaust pathway. A relief valve is designed to open at a specific pressure to help protect pumps and other equipment from exceeding stress limits. When pressure rises above the set limit, a safety valve can divert liquids, gases or a liquid-gas mixture to a flare header to help relieve pressure and normalize. Choose from relief valves with manual levers, spring-operated types and more at Grainger.
