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 control valve. Options include: the 6010 with integral outlet head; the 6011 pipe style; and the Whisper Disk.

• The diffuser concept is used in several unique versions; providing optimum solutions for various applications. The diffuser need not be installed adjacent to the control valve.
• A properly selected diffuser-valve combination can result in up to 40 dBA noise reduction.
• A diffuser-valve combination retains the pressure/flow control associated with a standard control valve. Just as important; it controls the generation of potentially damaging noise and vibration.
• All Fisher diffusers; both inline and vent; are ruggedly-built; static devices requiring no maintenance after installation. These features combine to offer increased noise control at a minimum investment.
