Fisher™ Whisper Trim™ I Cage

Fisher Whisper Trim I cages offer proven aerodynamic noise control that is effective for vapor, gas, or steam flow applications. The Whisper Trim I cage utilizes multiple orifices of a special shape, size, and spacing to minimize noise generated by the flow of vapor, gas, or steam through a control valve. Using a Whisper Trim I cage, in conjunction with a properly sized valve body, can substantially reduce the noise level below that of valves with standard trim.
