Consolidated boasts 140 years of dedicated pressure relief valve prv engineering and manufacturing expertise.

Dresser pilot operated safety relief valve.

The consolidated3900 series pilot operated safety relief valve is supplied with a non flowing pilot valve. Brands in the productrange of dresser valves are the maxi flow high pressure safety valve and the consolidated mpvtm modular pilot operated safety valve camflex and varimax eccentric plug rotary valves t ball rotary valves the svi digital positioner and process controllers. We know overpressure protection. The type 3900 modular pilot operated safety relief valve mpv features a separate non flowing pilot sub assembly design making it well suitable for use with both compressible and incompressible fluids optional pilot valve constructions offer either pop action or modulating action functionality to meet various pressure range seat tightness and blowdown requirements.

A pilot operated safety relief valve is a pressure relief valve in which the major relieving device is combined with and is controlled by a self actuated auxiliary pressure relief valve. This single pilot design is suitable for both incompressible and compressible applications and performs equally well on liquid vapor or two phase flow services. The set pressure will not require adjustment if the service condition changes. Pilot operated relief valves are available in both pop action and modulating action designs.
