Mitigate Industrial Valve Noise With<br>Fisher™ Whisper™ Technology Mitigate Industrial Valve Noise With<br>Fisher™ Whisper™ Technology

All plant personnel know that the risk of personal injury on the job can be high, but there is one hazard that is commonly overlooked — Valve Noise. Emerson’s new portfolio of additively manufactured noise reduction technologies is combatting employee hearing loss, equipment damage, and EPA noise regulation fines that can result from aerodynamic valve noise.

Our Complete Noise Solution Portfolio

<span style="color:#00488e;">Fisher™ Whisper™ NXV Trim</span>
Fisher™ Whisper™ NXV Trim
The Fisher Whisper NXV Trim is designed to reduce noise caused by rotary valves by up to 20 dB(A). It also provides up to 80% more noise attenuation than other rotary valves. Because of this high level of noise reduction, rotary valves can now be considered in processes previously requiring globe valves.

Key Features Include:
 
  • Optimized Inlet Contour minimizes capacity reductions and turbulent noise
  • Patented Elliptical Channels allow for optimal flow separation by changing the shape of the flow stream as the ball rotates
  • Channel & Hole Enhancements improve pressure distribution and reduce material velocities
  • Gas, Vapor, or Steam Compatible; available in multiple valve sizes and pressure class ratings
  • Rugged Fabrication provides structural integrity
<span style="color:#00488e;">Fisher™ Whisper™ NXG Trim</span>
Fisher™ Whisper™ NXG Trim
The Fisher  Whisper  NXG Trim reduces noise caused by globe valves and has 20% more flow capacity than other globe valves, without compromising noise reduction. This enables smaller valves to be used and saves space in the facility. It reduces noise by up to 30 dB(A).

Key Features Include:
 
  • Lattice Trim allows efficient jet management, more efficient dispersing exit flow, and reduced shear jet forces
  • Gas, Vapor, or Steam Compatible; available for multiple common valve sizes
  • Hardened Materials provide exceptional wear resistance
  • Quick Change Trim allows fast and easy inspection of the cage without removing the valve body from the pipeline
<span style="color:#00488e;">Fisher™ 6060 WhisperTube Modal Attenuator</span>
Fisher™ 6060 WhisperTube Modal Attenuator
The Fisher 6060 WhisperTube Modal Attenuator provides full pipe noise attenuation for locations downstream of control valves, regulators, pressure safety valves, and other noise sources. It can be paired with any kind of control valve or piece of equipment used in compressible fluid service to mitigate process noise without additional pressure drop or impact on process flow. It reduces noise by up to 15 dB(A).

Key Features Include:
 
  • Specially Engineered Acoustic Cavities treat noise via destructive interference
  • Straight-through Design resists pipe plugging/buildup and is compatible with pipeline pigging operations
  • Built-in Drain Channel interacts with each cavity, draining any liquid that enters the process
  • Application Versatility; designed for a wide range of fluid flow rates, pressures, and temperatures
  • Ease of Maintenance & Installation with the removable cylindrical stainless-steel screen and threaded lifting provisions
