CV3000-HTS single-seat regulating valves
Structural features and applied range
CV3000-HTS single-seat regulator valve core uses up-oriented structure, with compact structure, and have a "S" streamline channel, which reduces its loss of pressure drop, large flow, and wide adjustable, high flow characteristics accuracy, in accordance with IEC534-1-1976 standard. The leakage of regulator is accordance with ANSI B16.104 standard. Regulator equipped with multi-spring film actuator, with compact structure, large output.
The product conforms to the GB/T4213-92.
