HCB pneumatic cage type regulating valve

The HCB cage type double seat regulating valve is a pressure balancing regulating valve. The fluid channel of the valve body is S-shaped, and there is also a guide wing to improve the smooth flow of fluid around the sleeve. The advantages are small pressure drop loss, large flow rate, wide adjustable range, high accuracy of flow characteristic curve, good dynamic stability, low noise, and low cavitation corrosion. The regulating valve is equipped with a multi spring diaphragm actuator, which is compact in structure and has a large output force. Suitable for controlling high temperature and low temperature high pressure differential fluids.
