Description

The 77000 Series multi-stage expanding area control valve is designed primarily for high pressure compressible fluid or two-phase applications. It effectively controls erosion, vibration and high noise conditions, making it an ideal solution for high pressure, high temperature, flashing hydrocarbon liquid services. Typical applications for this design include a range from Hot High Pressure Separator control in Hydroprocessing applications to gas wellhead control in off-shore choke valves as well as a reliable solution for high pressure gas letdown with entrained debris.
