A complete line of Fisher inline diffusers provide optimum noise attenuation where valves can contribute substantial noise. When installed, the total pressure drop of the system is divided across the valve and diffuser. This enables the valve to operate at a lower pressure drop ratio, thereby lowering the noise level generated from the process flowing through the control valve. Options include: the 6010 with integral outlet head, the 6011 pipe style, and the Whisper Disk.
