Cage type two-seat regulating valve

The cage type two-seat regulating valve is a pressure balanced regulating valve. Its body fluid passage is S-streamlined. It also has a guide wing to improve the smooth flow of liquid around the sleeve. Its advantages are small pressure drop loss, large flow rate, wide adjustable range, high accuracy of flow physical curve, good dynamic stability, low noise and low cavitation corrosion. The control valve is equipped with multi-spring film actuator, which has compact structure and large output force.

Suitable for controlling high pressure differential fluid at high temperature and low temperature.
