The Valves are undoubtedly very useful...so useful that even our hearts have their own micro-sized valves! In industrial applications, control valves are often tasked with dissipating large amounts of energy. Despite the many advantages a properly trimmed valve may present, some of the energy dissipated is converted to noise energy which, when excessive, may cause severe auditory harm.
 

For stringent silencing requirements Fluid Kinetics has designed the Model CVS Control Valve Silencer which includes a high performance diffuser and an absorptive section. This combination silencer is capable of providing fluid-borne noise reduction up to 50 dB. (For moderate silencing see GDS).

Each CVS silencer is custom engineered for the particular installation. The diffuser drilling pattern is selected to provide a reshaped noise spectrum and optimum back pressure for the valve. The packed section is designed so that slot width and length can be varied to provide the correct attenuation of the diffuser noise spectrum.
 

FEATURES

Custom Acoustic Performance : The optimal combination of process conditions, performance requirements, slot width and packed length is used for each application to provide the required noise reduction.

Custom Flow Performance Design: Fluid Kinetics engineers design the diffuser and packed section to provide the exact amount of pressure drop required for each application. For high pressure and high noise application the diffusers can be designed to efficiently share pressure drop with the control valve. For low pressure drop requirements the silencers can be designed to minimize pressure loss.

Annular Core Construction: Heavy duty construction of the diffuser and packed section provide the exact amount of pressure drop required for each application. For high pressure and high noise application the diffusers can be designed to efficiently share pressure drop with the control valve. For low pressure drop requirements the silencers can be designed to minimize loss.

Triple Layer Pack Protection:  The long strand glass fiber acoustic packing material is protected by heavy gauge perforated facing, a layer of fiberglass cloth and a stainless steel screen. This triple protection prevents loss of packing into the gas stream.
