Cage type regulating valve is a pressure balanced regulating valve, which uses a sleeve guided pilot valve core as its internal components. It mainly utilizes the pressure of the fluid to achieve rapid action of the valve core with low operating force. In addition, the sealing type adopts a single seat seal, which has high accuracy in the flow characteristic curve and complies with the IEC534-1 standard. The regulating valve has good dynamic stability, low noise, air defense, and is suitable for controlling high-pressure differential fluids at various temperatures. Equipped with multiple spring film actuators or electric actuators, it has a compact structure and high output force.

The leakage rate meets the standard ANSI B16.104 Level IV and is less than 0.01% of the rated Cv
