Noise attenuation trim keeps valve packages compact
Controlling noise and vibration in power generation and other industrial applications is essential for enhancing equipment performance, extending operational lifespan, and complying with noise exposure limits. The new Noise Attenuation Trim from Celeros Flow Technology (Celeros FT) addresses all these issues and allows for smaller valves to be used – reducing costs without sacrificing performance.
The new trim has been developed by Copes-Vulcan (a Celeros FT brand). Pedro Flores-Castillo, Product Development Manager, Copes Vulcan, explained the impetus behind its introduction: “We are dedicated to supporting customers at every stage of their operations. Managing noise and vibration effectively improves equipment performance, enhances operational integrity and ensures long-term reliability. The Noise Attenuation Trim has been developed to enable more compact, cost-efficient flow control, while reducing wear and tear caused by noise and vibration. This not only boosts overall efficiency but also helps reduce energy consumption, leading to lower operational costs for plant owners and operators.”
Reducing noise, reducing costs
The Noise Attenuation Trim features an innovative patent-pending design and is precision-engineered to deliver advanced noise attenuation, superior control of vibration, and optimised flow capacity. Its unique flow pattern has been developed, tested, and field-proven using the latest digital modelling techniques to ensure the highest efficiency. A specific expansion factor facilitates fluid expansion and finer velocity control, and the impact of thermal expansion is mitigated through meticulous materials specification. This design ensures the valves are ready for even the most demanding applications, such as thermal solar power plants, where daily thermal contraction and expansion cycles can quickly degrade standard valves. The new trim is engineered with the latest technology to withstand such rigorous conditions, offering exceptional durability and longevity.
As a result, the Noise Attenuation Trim provides outstanding noise attenuation with no loss of capacity. The trim will therefore perform better for longer: reducing maintenance, optimising uptime, and lowering the total cost of ownership. In addition, the highly efficient trim design means that smaller valves can be specified – an important consideration in plants where space is at a premium. Using smaller valves also reduces the need for larger piping and infrastructure, resulting in a more compact and competitive package with lower installation costs.
Goodbye vibrations
The new trim offers an efficient means of meeting statutory noise exposure requirements, including Occupational Safety and Health Administration regulations. By lowering noise levels, the trim allows operators to work safely near valves for longer without the need for additional noise barriers.
It is also invaluable in urban or sensitive settings, where power plants or industry are located closer to residential neighborhoods. One example is energy-from-waste plants, which are becoming increasingly common in Scandinavia, Europe, and the UK. The Noise Attenuation Trim would also be beneficial in dedicated power plants adjacent to data centers, where sensitive electronic equipment must be protected from noise and vibration.
Easy upgrades
The Noise Attenuation Trim is specifically designed for use with the Copes-Vulcan range of Direct Steam Conditioning Valves (DSCV-SA/SR). It offers power plant operators and industrial users a practical and effective way to reduce noise without having to opt for high-end multi-stage trim designs used in larger conventional power stations.
The Noise Attenuation Trim provides a cost-effective solution that is simple to implement. Its cartridge design fits seamlessly into existing DSCV-SA valve bodies, which means existing DSCV-SA valves can be upgraded easily and cost-effectively.
