Whisper TrimIII Cages

Outstanding Noise Control—Use of a Whisper Trim III cage in a properly sized valve can result in a noise reduction up to 30 dBA compared to the same valve with standard trim.
Such a reduction would be similar to the reduction in noise level noticed when moving away from the noise source94m (308 feet).
Optimum Performance—Use of a Whisper Trim III cage provides excellent noise reduction and high flow capacity with the proven control and durability offered by standard Fisher valve trims.
The result: optimum overall performance at a minimum investment.
Easy Maintenance—Quick change trim allows fast and easy inspection of the cage without taking the valve body out of the pipeline.
Whisper Trim III is interchangeable with standard control valve trim.
Longer Trim Life—Hardened materials of construction are standard to provide exceptional wear resistance.
For more information about trim materials, see the appropriate valve body bulletin.
