Summary:
HCB cage type double seats control valve is a kind of control, valve with pressure balanced. The fluid channel is s-streamlined. It is equipped with turning vane to improve the smooth flow of fluid around the sleeve. It has advantages of small pressure rise loss, 1large flow, and wide adjustable range,. Besides, it has high accuracy of flow ,characteristic curv,e, good dynamic stability, low noise and small cavitation corrosion. The control valve is equipped with multi-spring diaphragm actuator or electnic actuator, and has compact structure, large output torque, which can easily control high pressure differential f[uid with high temperature or low temperature.
