Control Valve Noise Reduction

Control Valve Noise Reduction

Fisher noise-attenuation trims for control valves help provide the necessary degree of noise reduction for your application.

Understanding Control Valve Noise

Valves controlling high pressure drop liquids and gases can contribute substantially to ambient noise levels. The noise can be generated in three basic ways: by the mechanical vibration of valve components, by turbulent gas flow (aerodynamic noise), or by cavitating liquid flow (hydrodynamic noise).  If control valve noise is left untreated, it can introduce process control issues, pose safety risks to workers, or require costly repairs to valves, pipes, other instrumentation, and surrounding equipment.
