Fisher™ Whisper™ NXG Trim for Globe Control Valves – Advanced Noise Attenuation for Severe Service Gas & Steam Applications

Fisher Whisper NXG trim for globe control valves allows you to use smaller valves where previously capacity limited without reduction in noise abatement, providing 20% more flow capacity than the market. Using the Whisper NXG trim cage in conjunction with a properly-sized valve body can substantially reduce the noise level of the control application. Aerodynamic noise is generated by the turbulence created in the flow of vapor, gas, or steam as the fluid passes through a control valve.

Product Description

Overview: Engineered for Quiet Operation in Demanding Environments

The Fisher™ Whisper™ NXG Trim is a state-of-the-art noise attenuation trim specifically designed for globe control valves operating in severe service applications involving gases, steam, or vapors. In high-pressure drop scenarios, aerodynamic noise can pose safety risks to personnel and cause damaging pipeline vibration. This trim is engineered to mitigate these issues by significantly reducing the noise impact at its source, helping you ensure a safer work environment, protect your assets, and meet regulatory compliance.

By incorporating advanced design principles with robust manufacturing, the Whisper NXG trim delivers exceptional performance where it matters most.

Key Features & Benefits:

Superior Noise Reduction: Achieves significant noise attenuation, potentially reducing sound levels by approximately -18 dBA or more compared to standard trim, which can equate to a dramatic reduction in perceived loudness.
Robust Construction for Longevity: Designed with durability in mind, the trim utilizes hardened materials to provide excellent resistance to wear and erosion, extending service life and reducing the total cost of ownership.
Simplified Maintenance & Retrofit: Features a cage-style design that allows for quick inspection and replacement without removing the valve body from the pipeline. It is engineered for easy interchangeability with standard trim in many Fisher globe valve series, simplifying upgrades and maintenance procedures.
Proven Fisher Technology: Benefits from Fisher’s legacy of reliable flow control solutions, ensuring you receive a high-performance product backed by extensive engineering expertise.
Enhanced Process Stability: By minimizing noise and associated vibration, the trim contributes to more stable process control and protects downstream piping components.

Typical Applications:

The Whisper NXG Trim is ideal for a wide range of noisy gas and steam applications across various industries, including:

Power Generation: High-pressure steam letdown, turbine bypass systems.
Oil & Gas / Hydrocarbon Processing: Compressor anti-surge control, gas pipeline pressure reduction, export gas manifolds.
General Industrial Applications: Any process with high-pressure drops where aerodynamic noise is a concern.
