Cage Sleeve Control Valve

With sleeve guide structure and pressure balanced spool, it is specially designed for heavy duty service. With double seat seal, it is used for occasions where leakage requirements are not high. The valve body has a compact structure, and the flow channel is S streamlined.

There is a guide vane to improve the balanced flow of fluid around the sleeve. The advantages are that the pressure drop loss is small, the flow rate is large, the adjustable range is wide, and the flow characteristic accuracy is high. The valve core adopts a pressure balance structure, which can control high pressure and other working conditions through the light and small thrust of the actuator. Widely used in pipeline fluid control requiring good dynamic stability, high temperature and high pressure. Cage guide, large guide area, good stability;
