Fisher™ WhisperFlo™ Aerodynamic Noise Attenuation Trim
Model: WhisperFlo
Provide additional attenuation for aerodynamic noise in very demanding vapor or gas applications with high-pressure drops.
Control Valves
Fisher WhisperFlo trim represents state-of-the-art solutions for applications that demand noise attenuation. Control valves with WhisperFlo trim provide additional attenuation for aerodynamic noise in very demanding vapor or gas applications with high pressure drops. A WhisperFlo cage with an appropriately sized valve body is designed to reduce the noise level up to -40 dBA. For special applications, -50 dBA attenuation can be achieved
Key Features
- Use of WhisperFlo trim provides excellent noise attenuation for very demanding applications. It should be considered for those applications that more conventional solutions cannot reach.
- Quick change trim allows fast and easy inspection of the cage without taking the valve body out of the line. WhisperFlo trim is interchangeable with standard control valve trim.
- Hardened materials or a unique wear surface construction are standard to provide excellent wear resistance. The three dimensional flow path, pressure-staging, and special passage shapes uniquely combine to equalize energy dissipation.
- WhisperFlo trim has higher capacity at conventional valve travels and port sizes than tortuous path designs.
- Standardized port sizes provide capability to retrofit existing valves.
