Product details

HCB balance cage regulating valve is an improved pressure balance regulating valve. The valve sleeve is equipped with a high-performance sealing ring, which effectively improves the leakage level. The valve fluid channel isSStreamlined and equipped with a guiding wing to improve the smooth flow of fluid around the sleeve, the advantages are low pressure drop loss, large flow rate, wide adjustable range, high accuracy of flow characteristic curve, good dynamic stability, low noise, and minimal cavitation corrosion. The regulating valve is equipped with a multi spring thin film actuator, which has a compact structure and high output force.
