Product Description

Fisher Vee-Ball Series valves (V150, V200, and V300) with the Whisper Trim combines the efficiency of a rotary valve with the acoustical attenuation capability of Whisper technology to provide improved performance in applications where aerodynamic noise is a concern. The Fisher Whisper Trim can be utilized in gas and vapor service to reduce noise effects that pose safety risks to personnel and cause pipeline vibration.
