Anderson Greenwood Series 90/9000 Pilot Operated Pressure Relief Valves
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.
