SYCB high-performance cage type double seat regulating valve is a pressure balanced regulating valve. The fluid channel of the valve body is S-shaped and equipped with a guiding wing to improve the smooth flow of liquid around the sleeve. Its advantages include low pressure drop loss, large flow rate, wide adjustable range, high accuracy of flow characteristic curve, good dynamic stability, low noise, and small cavitation corrosion. The regulating valve is equipped with a multi spring thin film actuator, which has a compact structure and high output force. Suitable for controlling high temperature and low temperature high-pressure fluids.
