CV3000-HCB cage regulative valves
CV3000-HCB cage control valves

structural features and applied range

CV3000-HCB cage regulator is pressure balanced regulator, trims use socket oriented guide valve core, it mainly uses fluid pressure to realize valve core rapid movement, operating force is small. In addition, sealing type uses single seat sealing, high precision flow characteristic curve, in accordance with IEC534-1 standard. Regulator dynamic stability is good, noise is low, and air defense, it is suitable for controling kinds of temperature high pressure difference flow. Equipped with electric actuators, its structure is compact, and output is large.
The product conforms to the GB/T4213-92.
