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

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.
A new generation packed with performance
Aug 11, 2021
As always, the latest generation of Neles Neldisc™ metal-seated and Jamesbury Wafer-Sphere™ soft-seated butterfly valves is built to perform. The modular valve platform leans on field-proven technologies and decades of experience and expertise to meet the challenges of modern industrial processes.
Reliable performance with unique metal seat technology
Jul 7, 2021
When we talk about long-lasting performance in regards to our modular butterfly valves, we are talking about long term reliability and a valves ability to maintain the same high-quality performance across its entire operational life cycle.
The butterfly valve for any given situation
Jun 7, 2021
As the needs and requirements of modern process industries continue to change and become ever stricter, the role of safe and efficient valve solutions keep growing. The sustainable butterfly valve platform, which includes the metal-seated Neles Neldisc™ and soft-seated Jamesbury Wafer-Sphere™ valves, have been designed and developed over time to address today’s needs and challenges.
Still setting the standard for soft-seated butterfly valves
Jun 29, 2021
While the demands for industrial soft-seated butterfly valves continue to evolve, new features and innovations are needed. At the same time, the fundamental design of the Jamesbury™ Wafer-Sphere™ butterfly valve continues to prove itself in action in many of the most demanding applications. The patented and often imitated double-offset design originated by Valmet's flow control business continues to be the industry benchmark for performance excellence.
Our butterfly valves are designed to be as compact and lightweight as possible. This creates savings on both raw material consumption and energy needed for transport, which lowers the manufacturing and logistics chain's environmental impact and carbon footprint. The optimized weight and dimensions also make for easier and safer installation, replacement and maintenance.
Our Neldisc and Wafer-Sphere valves come equipped with the highest Cv on the butterfly valve market. With significantly lower pressure losses comes the lower need for pumping energy. This spells out energy savings that make your process more environmentally friendly and more profitable. The high Cv can also mean sizing down on your valves and thus also your actuators.
Our high-quality butterfly valves also have a lower torque need, which in cases may allow you to select and install a smaller actuator as a part of your valve assembly. This helps improve process sustainability and deliver capital savings. It allows you to reduce everything from weight and the need for additional piping support, to process vibrations and process air consumption. Again, this means lower energy consumption.
Butterfly valves are extremely versatile and suitable for many control and shutoff applications. These quarter-turn valves open and close by turning the disc 90° inside the flow port. Butterfly valves are compact and lightweight in comparison to many other valve types and still, they can handle harsh conditions and processes. Low torque requirement, wide controllable range and tight shutoff create a unique combination of features for sustainable process control.
Designs ranging from lined utility valves to high-performance triple offset butterfly valves with full metal sealing, ensure a cost-effective and space-saving solutions for almost every industry, application and flow media.
