CV3000-HCN Low Noise Cage Regulative Valve

CV3000-HCN Low Noise Cage Regulative Valve

Structural features and applied range

CV3000-HCN low noise cage regulator, can reduce the noise of compressible fluid, for gas diffusion and throttling expansion, the sleeve has many symmetrical holes to reduce the pressure drop. The valve core adopts pressure balance structure. Fluid passage in an s-shaped streamline, also has a contra-vane which improves the balance of fluid flow around the sleeve, make the loss of pressure drop small, flow is large, and noise is low. Regulator equipped with multi-spring diaphragm actuator, which structure is compact and output is large.
The product conforms to the GB/T4213-92.
