Aerodynamic Noise Control
Control valve technologies used to reduce the noise (sound pressure level) of compressible flows via one or more techniques of frequency shifting, discrete pressure staging, trim passage shape and/or adequate expansion areas.
 | For decades Emerson's severe service team has been providing global customers with Fisher severe service control valve solutions. |
 | Vent silencers and line silencers provide the solution to high intensity, broadband noise associated with pressure relief systems and gas/steam line turbulence. |
 | Severe service cages provide effective attenuation of aerodynamic noise in vapor, gas, or steam applications involving high pressure drops or high pressure drop ratios. |
 | Severe service vent diffusers are a solution for applications with high noise potential due to low downstream pressure and high pressure drop, throttling generated noise as a function of pressure drop. |
