Flow balancing

Valmet expanded its offering with flow control solutions in April 2022, when the industrial flow control company Neles was merged into Valmet. In June, the company broadened its new generation versatile butterfly valve product range with the Neles^TM Q-Disc^TM, a new high-performance feature to help flow balancing in control valve applications. But what makes the new Q-Disc a game-changer? Let’s take a closer look at the Q-Disc design journey to find out.

The Q-Disc flow balancing trim addresses dynamic torque-related challenges in butterfly valve applications. The perforated trim plate is seamlessly integrated with the disc, making it durable, efficient and easy to incorporate into your valve assembly. Q-Disc has been designed to be easy to install, service and maintain as a part of versatile Neles Neldisc^TM and Jamesbury^TM Wafer-Sphere^TM butterfly valves. It also provides market leading noise reduction even up to 12 dB.

Neles, now Valmet’s Flow Control Business Line, has a long history in bringing reliable and innovative flow control solutions to the market. In addition to decades of engineering know-how, our design process is based on continuous dialogue with customers, combining experience from tens of thousands of customer installations and translating them into solutions that answer to specific needs of specific industry and process. In the case of Q-Disc, one of the key drivers was to improve process performance in demanding control valve applications that involve challenging media or process conditions, for instance. We also build on and get inspiration from existing innovations: the Q-Disc, for example, helps reduce noise and cavitation like all the other Neles trims under the Q-moniker.

Tackling the dynamic torque

Dynamic torque is a challenge that all rotary valves, especially butterfly valves, face when in active flow control service. However, it is an aspect that is not as often taken into consideration when designing valve solutions and selecting the right configurations …
