CV3000-HCP balance cage signle seat control valves
structural features and applied range
CV3000-HCP balance cage single-seat regulator controls kinds of high temperature, low temperature, high pressure fluid, is a balanced regulator. Valve has compact structure, "S" streamline channel, and a contra-vane which impoves the balance of fluid flow around the sleeve, reducing the loss of pressure drop, flow is large, and wide adjustable rang, high accuracy of flow characteristics, it conforms to IEC534-1-1976 standard. Regulator dynamic stability is good, and noise is low, also with small cavitation erosion. The leakage of regulator in accordance with ANSI B16.104 ANSI standard. Regulator equipped with muti-spring diaphragm actuator, its structure is compact, and output is large.
The product conforms to the GB/T4213-92.
