Global technology and services provider Metso Corporation’s new Neles Q2-Trim technology reduces noise by up to 30 dB compared with a typical control valve, helping process indus- try customers improve personnel and plant safety, while simultaneously increasing efficiency and reliability.
“For more than 30 years, Metso’s patented Q-Trim technology has been the industry benchmark for rotary noise attenuation solutions in challenging applications. Metso has added a new level of performance with the new Neles Q2-Trim, which solves aerodynamic noise problems,” the company states.
The Q2-Trim technology is a combination of various techniques, resulting in multiple benefits for customers. By eliminating the damage that high noise levels can cause to process plants, employees and their surroundings, Q2-Trim ensures a safe working environment for personnel, as well as stable process control and longer uninterrupted plant runtime.
By reducing noise and related vibration to acceptable levels, Q-Trim technology also protects process equipment, which, in turn, lowers the operating costs and reduces the need for spare parts for valves and other accessories.
Combining Q-Trim technology with quarter-turn valves results in emission levels that meet all relevant industry standards. Compact size and selection of mounting positions means less pipeline support and easier piping layout design.
The Neles Q2-Trim is an addition to the existing Q-Trim technology and is available for pressure classes ASME 150 – 600 in sizes ranging from 2 inches to 16 inches, and PN 10 to PN 100 in sizes DN 050 to DN 400 in standard ball valve offering. The standard Trim material is stainless steel; however, Q-Trim products made from special alloys and larger sizes are available on request. Q2-Trim has several key applications in various fields in the power, oil and gas, petrochemicals, industrial gas and chemicals industries.
