HCB type electric intelligent cage type regulating valve

The structural characteristics and application range of HCB cage type regulating valve CV3000-HCB cage type regulating valve is a pressure balanced regulating valve, and the valve internals adopt a sleeve guided pilot valve core. It mainly uses the pressure of the fluid to achieve rapid action of the valve core with low operating force. In addition, the sealing type adopts a single seat seal, which has high accuracy in the flow characteristic curve and complies with the IEC534-1 standard. The regulating valve has good dynamic stability, low noise, air defense, and is suitable for controlling high-pressure differential fluids at various temperatures. Equipped with multiple spring film actuators or electric actuators, it has a compact structure and high output force. This product complies with GB/T4213-92.
