By combining robust construction with precision engineering, the Whisper NXV Trim helps you achieve higher performance, ensure a safer working environment, and meet regulatory compliance.
Proven Noise Reduction: Delivers a noise attenuation performance of up to -20 dBA, depending on specific service conditions, significantly reducing the impact of aerodynamic noise.
Robust Additive Manufacturing: The noise attenuator is built using additive manufacturing with durable welds, ensuring the structural integrity of the valve ball for long-lasting performance.
Excellent Flow Characteristic: The precision-profiled V-notch ball provides a modified equal percentage flow characteristic, offering superior control and predictable performance.
Enhanced Environmental Protection: An optional ENVIRO-SEAL™ packing system is available to control valve emissions below the U.S. Environmental Protection Agency (EPA) limit of 100 ppm.
Easy Integration: Designed as a complete solution for the V150, V200, and V300 Vee-Ball valve series, combining flow control and noise reduction in one efficient package.
The Whisper NXV Trim is ideal for a wide range of noisy gas and vapor applications across various industries, including:
Oil & Gas / Hydrocarbon Processing: Pressure reduction stations, gas venting.
Power Generation: Steam distribution, turbine bypass.
General Industrial Applications: Any process with high-pressure drops in gas or vapor service where aerodynamic noise is a concern.
