5624 Low-Noise Cage type Control valve

Type 5624 Low-Noise Cage type Control valve is designed to reduce the noise. To adjust the gas spreading and expanding, the cage is designed with many symmetrical orifices to reduce the pressure. The flow channel is S type with a guiding flow wing which can improve cage’ stable motion, and it makes the small pressure gap, high flow and small noise. The valve disc adopts pressure balanced structure. It is equipped with muti-spring diaphragm actuator with compact structure and large output force.
