Improving process performance


Valmet is extending its versatile butterfly valve product range with Neles Q-Disc, a new high-performance feature to help flow balancing in control valve applications.

«The modular butterfly valve range was developed to help our customers with their valve selection not only for typical application challenges, but also to solve problems in complex process conditions» says Taija Hämäläinen, Head of butterfly valve products at Valmet. «Q-Disc is specifically designed for control applications. One of its key benefits is that it helps avoid oversized actuators for control valve packages, and thus it provides a solution that is more cost- and energy efficient. The Q-Disc feature offers our customers a best-in-class flow-balancing solution and excellent controllability to improve overall process efficiency, » Hämäläinen continues.

Q-Disc is a problem solver for challenging flow conditions. It can be used to avoid cavitation in low opening angles, and it also provides market-leading noise reduction capabilities – even up to 12 dB in certain flow conditions.

«Q-Disc also helps in optimizing the entire valve-actuator package by helping reduce the impact of dynamic torque caused by the flow, providing improved reliability and efficiency for the overall process the valve is part of» says Hämäläinen.

Q-Disc is available as modular option for a wide range of butterfly valves, and it can be used for a temperature range up to +600 °C.

The Neles Q-Disc allows efficient flow balancing in demanding control valve applications. The new high-performance feature is available as a modular option for a wide range of Neldisc and Wafer-Sphere butterfly valves. Q-Disc also provides market-leading noise reduction capabilities.
