DCN low -noise cage control valves is designed to remakably reduce aucoustic noise in services of compressible .The cage has a large number of small holes and renders and renders an ideal pressure reduction with a combination in two steps of “restriction”and “diffusion and expansion ”.The fluid passge is desigend in S-shape with low pressure and a stabillizer is provided as a stainer for flow near the cage ，thereby prmitting a large Cv valve 。 The valve is actuated by a new compact and poweful acttuator loaded with multiple springs .The DCN Valve suitable especially for control of process fluids of a wide ranges of temperature and pressure or pressure where a low noise and high dynamic stablility are required .
