Meet Our New Noise Attenuation Trim: Compact, Cost-Effective, and Built for Performance

08/05/25

Controlling noise and vibration in power generation and many industrial applications is not just a nice-to-have—it is a must-have. It keeps the plant running smoothly, extends equipment lifespan, and ensures compliance with noise regulations. We have introduced a new Noise Attenuation Trim to tackle noise and vibration head-on while allowing for smaller, more cost-efficient valve packages.

Developed by our trusted brand Copes-Vulcan, the new trim is designed to deliver advanced noise control without compromising on performance. And here is the best bit: it helps reduce costs by enabling the use of smaller valves, all while maintaining the same high standards of efficiency and reliability.

Pedro Flores-Castillo, our Product Development Manager, Copes Vulcan, shared the thinking behind this new development:  "As a global lifecycle partner, we’re committed to supporting our customers at every stage of their operations. Managing noise and vibration effectively doesn’t just improve equipment performance—it also enhances reliability and reduces wear and tear. Our Noise Attenuation Trim is all about delivering compact, cost-efficient flow control while helping operators reduce energy consumption and operational costs."

Smaller valves, bigger benefits

The Noise Attenuation Trim is packed with engineering innovation. Its patent-pending design delivers exceptional noise reduction, superior vibration control, and optimized flow capacity. Its stand out qualities include:

• Advanced flow design: A unique flow pattern ensures maximum efficiency, with a specific expansion factor for finer velocity control.
• Durability under pressure: the new trim is built to handle the toughest conditions, like the daily thermal expansion and contraction cycles in thermal solar power plants.
• Compact and cost-effective: Smaller valves mean less space, smaller piping, and lower installation costs—perfect for plants where space is tight.

And the best part? This trim does not sacrifice performance for size. It delivers outstanding noise attenuation with no loss of capacity, meaning it performs better for longer, reduces maintenance needs, and optimizes uptime; resulting in a win-win for plant operators.

The Noise Attenuation Trim also simplifies compliance with noise regulations, enabling operators to work safely near valves without additional noise protection. By reducing noise and vibration, it safeguards both people and sensitive equipment, making it a versatile solution for most applications. Examples include dedicated power plants near data centers, where sensitive electronics need shielding from vibration, and community-based energy-from-waste plants.

Easy upgrades

One of the most practical features of the Noise Attenuation Trim is how easy it is to implement. Designed specifically for the Copes-Vulcan Direct Steam Conditioning Valves (DSCV-SA/SR), the trim’s cartridge design fits seamlessly into existing valve bodies. This means operators can upgrade their current DSCV-SA valves without the need for costly overhauls or high-end multi-stage trim designs. 

Whether it is cutting noise, reducing costs, or optimizing performance, the Noise Attenuation Trim is a smart solution for today’s industrial challenges. It is built to handle demanding applications, protect sensitive environments, and deliver long-term value for plant operators. In short, this trim is not just about noise—it is about smarter, more efficient operations.
