HCB cage two-seat control valve is a pressure balance of the control valve, the valve body fluid channel was S streamlined, but also has a smooth flow around the sleeve of the flow of the flow of the wing, the advantage is the pressure drop loss, , Adjustable wide range of flow characteristics of high precision curve, good dynamic stability, low noise, small cavitation corrosion. Regulating valve with multi-spring film actuator, compact structure, the output force. Suitable for high temperature, low temperature of the high pressure fluid.
