Low Noise Cage Type Control Valve

low noise cage type control valve is mainly designed to reduce the noise of compressible fluid, and to adapt the gas throttle diffusion and expansion. The sleeve is provided with many symmetrical holes to reduce the pressure drop. The fluid passage is s–streamlined. It is equipped with turning vane to improve the smooth flow of fluid around the sleeve. So that the control valve has small pressure drop loss, large flow, and small noise.

The valve core adopts pressure balance structure. The control valve is equipped with multi–spring diaphragm actuator or electric actuator, and has compact structure, large output torque.
