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 Fisher™ Inline Diffuser is a high-performance valve trim component engineered to deliver precise flow control and conditioning within a pipeline. Designed for integration into control valve assemblies, this trim is ideal for applications requiring enhanced process stability, reduced noise, and minimized erosion in severe service conditions. By efficiently managing pressure drops and optimizing fluid dynamics, the Inline Diffuser helps protect downstream equipment and extends the service life of your valve, ensuring reliable performance in demanding industries such as oil and gas, power generation, and chemical processing.
Superior Flow Conditioning: The engineered design of the Inline Diffuser ensures a more uniform flow profile, which contributes to improved process control and measurement accuracy.
Effective Noise and Erosion Reduction: By controlling velocity and staging pressure drops, this trim significantly mitigates aerodynamic noise and protects valve and pipeline components from the damaging effects of cavitation and erosion.
Robust Construction for Longevity: Manufactured from durable, hardened materials such as stainless steel, the Inline Diffuser is built to withstand abrasive and corrosive services, ensuring extended service life and reduced maintenance costs.
Easy Integration and Maintenance: Designed as a trim component for Fisher control valves, it allows for straightforward installation and service, helping to minimize system downtime.
Versatile Application: Suitable for a wide range of media, including water, steam, and various process gases, making it a flexible solution for diverse industrial needs.
The Fisher Inline Diffuser is suited for a variety of demanding applications, including:
Pressure Reduction Stations in oil and gas transmission
Steam Letdown Systems in power generation and industrial plants
Process Control Valves in chemical and hydrocarbon processing industries
High-Pressure Drop Applications where noise and erosion are primary concerns
