Q-Trim valves
Q-Trim valves
Q-Trim valves optimize noise and cavitation attenuation, allow dirt to pass, allow a wide range of operations and keep dimensions, weights and costs reasonable. Q-Trim attenuates sound by up to 30dBA and vibration by 90% and more.
For over 30 years Neles Q- Trim has been the noise attenuation solution. The noise abatement laws and health and safety legislation are becoming increasingly strict. Metso introduces Q2- Trim, the optimum solution for noise problems, that at the same time fulfills all legislative requirements and customer needs.
The new Q2- Trim offers multiple advantages:
- Ensures a safe working environment
- Protects the process plant and surroundings
- Enables stabile process control and longer uninterrupted plant runtime
- Fulfills all legal requirements
The Q2- Trim principle
Neles Q2- Trim takes the patented Q-trim technology to new level. The technology is a combination of various techniques:
- Pressure staging
- Flow division
- Peak frequency shifting
- Velocity control
With new Q2- Trim technology, the noise reduction can be up to -30 dB(A). This creates the optimum solution for noise attenuation. Without detached resistors the valves with Q2- Trim are easy to install and fit onto the pipeline. The benefits of a compact valve size include a decreased need for pipeline support and more options for mounting positions.
