General
JPCN Low-noise Cage Guided Control Valve can reduce the noise of compressible liquid. In order to meet the gas throttle diffusion and expansion, the cage with many symmetrical holes on it to reduce pressure drops. The valve plug is the pressure balanced type. The valve with a compact structure, S type flow way and a guide wing that improved the fluid balance around the cage makes the low pressure loss, large flow and low noise are available.
