Improved process efficiency with high-performance butterfly valves

Sep 13, 2023

Process efficiency can be defined as optimal flow capacity, minimized emission and leakage, and low energy consumption. At the same time, the first two contribute to the last – but not least: low energy consumption.

Valmet butterfly valves deliver versatility and performance for severe service applications

Nov 18, 2021

Their compact and lightweight design, availability in larger sizes and easy usability make our butterfly valves an attractive option for many industrial processes. Their versatility makes them suitable for a wide range of temperatures, pressures, industries, and applications. They can be used in either control, on-off or emergency shutdown service.

Sustainability through long-lasting efficient performance

Oct 19, 2021

The sustainable performance of a butterfly valve is dependent on a number of important factors. In essence, a valve that can maintain safe and efficient performance over its extended lifecycle is inherently sustainable. This means minimizing both internal and external leakages as well as the risk of failure in demanding service.

Testing and simulations guarantee reliable process efficiency for valves

Sep 21, 2021

Want to know how superior product design is achieved? High quality and robust design reflect on the reliability and performance of valves. We interviewed Tommi Bergström, Manager, Engineering Analysis, about the design process behind the new modular butterfly valve platform.

What’s driving sustainable development in valve technologies?

Sep 2, 2021

When we look at valves from the sustainability point of view, three key aspects stand out clearly at the forefront: emissions, internal tightness and a lifecycle view. In all three cases industry standards and regulations play an important role in driving development and ensuring the environmental performance of industrial processes.
