Cage Type Double Seat Control Valve Stainless Steel Valves 40-200mm Nominal Diameter

HCB cage-type double-seat control valve

The HCB cage-type double-seat control valve is a pressure-balanced control valve. The fluid channel of the valve body is S-streamlined, and it is also equipped with a guide vane that improves the smooth flow of fluid around the sleeve. It has the advantages of small pressure drop loss, large flow rate, wide adjustable range, high precision of flow characteristic curve, good dynamic stability, low noise, and little cavitation corrosion.

The control valve is equipped with a multi-spring diaphragm actuator, which has a compact structure and large output force. It is suitable for controlling high-pressure difference fluids at high or low temperatures.
