Fisher Whisper Trim lll Cage

Fisher™ Whisper Trim lll cages provide effective attenuation of aerodynamic noise in vapor, gas, or steam applications involving high pressure drops or high pressure drop ratios. Using a Whisper Trim lll cage in conjunction with a properly-sized valve body can substantially reduce the noise level of the control application. Aerodynamic noise is generated by the turbulence created in the flow of vapor, gas, or steam as the fluid passes through a control valve.
