Fisher Diffuser

A vent diffuser places back pressure on the control valve while venting process to the atmosphere and shares the total pressure drop with the vent valve. This reduces the vent valve noise and noise at the atmospheric vent point. Fisher 6013 vent diffusers come with an outer shell attached for use in sky vent applications in power plants.

Fisher Inline Diffusers 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

A complete line of Fisher inline diffusers provide optimum noise attenuation where valves can contribute substantial noise.

Inline Diffusers Fisher 6010, 6011 and Whisper Disk inline diffusers are Fisher 6012 and 6013 figure 1 vent diffusers reduce the noise generated by the venting of compressible fluids to atmosphere.

Type 6010, 6011, and Whisper Disk Inline Diffusers Because valves can be substantial noise contributors when controlling industrial processes, a complete line of Fisher diffusers is offered to provide optimum noise attenuation. A diffuser is a pressure-reducing device that is installed downstream from the control valve. The total pressure drop of the system is divided across the valve and a
