Feature:
• The multi-stage cage structure is used to reduce pressure.
• Features include an S-shaped passageway and a high coefficient of flow (Cv).
• The valve plug is designed with a balanced structure, making this pressure-independent control valve primarily suitable for high-pressure compressible fluid or two-phase applications.
• It effectively controls erosion, vibration, and high noise conditions, making it an ideal choice for high-pressure, high-temperature, flashing hydrocarbon liquid services.
• Typical applications of this design range from hot high-pressure separator control in hydroprocessing applications to offshore choke valves for gas wellheads, as well as a reliable solution for high-pressure gas letdown with entrained debris.
