■ Overview

HCP balanced cage single seat regulating valve is one of the CV3000 series products.

The HCP balanced cage single seat regulating valve is an improved pressure balanced regulating valve that uses high-performance sealing rings on the valve plug or sleeve, effectively increasing the leakage level. The valve structure is compact and has an S-shaped streamlined shape

The 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, in compliance with the IEC534-2-1976 standard. The regulating valve has good dynamic stability, low noise, and minimal cavitation and corrosion. 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 with the GB/T4213-92 standard
