Cage control valve

Cage type regulating valve is a pressure balance type regulating valve. The valve internals adopt sleeve guided pilot valve core. It mainly uses the pressure of fluid to realize the rapid action of valve core, and the operation force is small. In addition, the seal type adopts single seat seal with high accuracy of flow characteristic curve, which conforms to iec534-1 standard. The control valve has good dynamic stability, low noise and air defense. It is suitable for controlling high pressure differential fluid with various temperatures. Equipped with multi spring film actuator or electric actuator, it has compact structure and large output force.
