■ overview

HCBThe balanced cage type regulating valve isCV3000One of the series products.

HCBThe balanced cage type regulating valve controls various high-pressure fluids at high and low temperatures, and is a pressure balanced regulating valve. The valve structure is compact, There is a presentationSThe streamlined channel is also equipped with a guide vane that improves the fluid balance flow around the sleeve, resulting in low pressure drop loss, high flow rate, wide adjustable range, and high accuracy of flow characteristics, which meets the requirements ofIEC534-2-1976Standard. The regulating valve has good dynamic stability, low noise, and minimal cavitation and corrosion.

The leakage of the regulating valve meets the requirementsANSI B16.104Standard. The regulating valve is equipped with a multi spring diaphragm or cylinder actuator, which has a compact structure and high output force. This product complies withGB/T4213-92Standard.
