Repeat valve order for Metso

Hydrocarbon Engineering,

Metso has been awarded a significant repeat order for Neles® ball valves with Neles Q-Trim noise attenuating technology from a North American pipeline owner that brings crude oil from Canada to refineries in the US. By reducing cavitation, noise and related vibration to acceptable levels, Q-Trim technology protects process equipment, thus lowering the operating costs and minimising the need for valve spare parts and other accessories. This, in turn, means lower total costs of ownership.


Kyle Rayhill, Global Business Manager, Neles & Mapag, Automation, Metso said, ‘the savings achieved for this customer with Metso’s solution are estimated to amount to millions of dollars per year thanks to the higher efficiencies from our technology. It really pays off to deal with the noise problem even before it is created. Elevated control valve noise in the throttling process can be harmful not only to employees and surrounding communities, but it can also seriously damage process equipment. Once noise is created, it is hard to eliminate.’

Q-Trim technology

For more than 30 years, Metso’s patented Q-Trim technology has been the industry benchmark for rotary noise attenuation solutions in challenging applications. Recently, Metso added a new level of performance by introducing Nelese Q-Trim that solves aerodynamic noise problems and reduces noise up to 30 decibels compared with a typical control valve.

This technology is a combination of various techniques, including pressure staging, flow division, peak frequency shifting and velocity control. Metso has recently added the new Neles Q2-Trim, thereby extending the family of Q-Trim product capability up to 30 dbA. The full range of Neles Q-Trim is available for pressure classes ANSI 150 through 900.
