Mitigate Industrial Valve Noise with Fisher™ Whisper™ Technology

February 21, 2024
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

Fisher™  Whisper™ NXV Trim

Fisher™ Whisper™ NXV Trim

Rotary valve trim 

  • Provides up to -20 dB(A) acoustical attenuation and 80% more noise attenuation than other rotary valves
  • 3D design minimizes flow capacity reductions, improves pressure distribution, and optimizes flow separation 
Fisher™  Whisper™ NXG Trim

Fisher™ Whisper™ NXG Trim

Globe valve trim

  • Allows for up to 30 dB(A) noise reduction and 20% more flow capacity than previously possible 
  • Quick change lattice trim eliminates jet structure limitations and increases flow capacity
