77003 Series Multi-Stage Valves (Angle/Globe)

The 77003 Series multi-stage, expanding area control valve is primarily for high-pressure compressible fluid or two-phase applications.

It controls under conditions such as flow-entrained debris, damaging vibration, and high noise, 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 well-head control in off-shore choke valve applications as well as high-pressure gas letdown with entrained debris.
