Maximize operating pressure and minimize emissions with the Series 90/9000 pilot operated relief valve; a high performance alternative to weight loaded relief devices

Pilot control keeps high seat forces all the way to set pressure point, helping eliminate product losses.Snap action opening permits full opening at set pressure, allowing higher settings and overcoming freezing or sticking problems.Choice of rapid snap opening and proportional modulating action pilots to suit the process.Extensive selection of resilient seat and diaphragm materials to meet most conditions and provide long maintenance free operation.Balanced against back pressure enabling connection to closed header systems without loss of valve lift or set pressure fluctuations.Remote sensing option allows accurate pressure sensing regardless of inlet piping pressure losses.Field test connection enables valve function verification in place without removal to a test bench or raising process pressures.Manual blowdown enables manual or remote actuation to depressurize a system.ASME UV Code Stamp for set pressures above 15 psig.
