These valves are designed to protect pipelines, tanks or any other device against pressure increase. The robust construction of these valves ensures reliability in the rigorous service of municipal and industrial applications.
The valves opens at a reach set pressure level and allows fluid to escape and release pressure immediately. The pressure relief valve can be easily set, service, and clean. The valves are designed with 2 ports, the 3 ports model design is available on request.
The valve size depends on flow capacities vs set pressure in order to ensure the equipment protection. For the increase of pressure, the valves can also work as backpressure relief valves.
The relief valve is designed to operate with liquids and has the advantage of chemical resistance material properties of PTFE and PVDF.
The valves are available from ½” to 4” bsp or npt threaded ends or EN & ANSI flanged ends on demand (subject to quantities).
