Sustainability through long-lasting efficient performance
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.
Minimizing external and internal leakages
Neles Neldisc™ and Jamesbury Wafer-Sphere™ valves are approved for both the API 607 and ISO 15848-1 certifications. This means that they have been tested and proven to provide both excellent fire safety and the lowest possible fugitive emissions. We design and manufacture all of our valves to meet the most stringent standards and regulations. Meeting these universally accepted major standards often allows for the valves to also meet many of the other local and regional standards in use around the world.
A tight seal within the valve eliminates losses and waste in terms of both flow media and the energy consumption related to pumping. These valves continuously prove their excellent tightness in operation, in both high-pressure and low-pressure applications. Both the metal-seated Neldisc and soft-seated Wafer-Sphere achieve ISO 5280 Rate A tightness and zero seat leakage as stipulated by the API 598 certification standards.
Reducing energy consumption
Energy consumption has long been one of the most recognized areas where the sustainable performance of industrial processes can be improved. One important sustainability attribute related to energy consumption and process efficiency has to do with the low torque requirement of these valves. Thanks to the unique double and triple offset valve designs much less torque is required to achieve a reliable tight seal.

The lower torque requirement directly reduces the consumption of pressured air, allowing for the use of smaller pneumatic actuators as a part of the valve assembly. By sizing down on the actuator, greater energy efficiency can be achieved in the process, not to mention the economic savings this implicates.
Extending service life
Extending the lifecycle of valves helps reduce environmental impact in several ways. Not only does it reduce the amount of material usage and the effects of valve construction, but also the environmental impact of service operations. Thanks to our design, both the sealing ring and disc are subjected to less wear during regular operations. This reduction in wear comes from the seal profile and the careful selection of sliding pairs in metal-to-metal contact.
Even valves with the most long-lasting tightness require service and maintenance from time to time. The modular construction of the Neldisc and Wafer-Sphere butterfly valves also allows for the easy service and upgrade of single components such as seats or discs, rather than replacing entire valves. Yet again, this is one more example of sustainable practices that help reduce the use of materials and resources.

Versatility and sustainability through modularity
What does future-proof technology mean? And how to achieve versatility and sustainability through modularity? Learn more from the article by Taija Hämäläinen, Director, Butterfly Valves Product Line at Valmet.
Valmet butterfly valves deliver versatility and performance for severe service applications
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.
What’s driving sustainable development in valve technologies?
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.
One butterfly valve, many uses
Did you know we have nearly a century of combined experience with Neldisc™ metal-seated and Wafer-Sphere™ soft-seated butterfly valves? Today we talked with Petri Ilonen, Product Manager for butterfly valves, about the new modular butterfly valve platform that we have recently introduced. Watch the video interview below to learn more.
A new generation packed with performance
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
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.
Safer butterfly valves are made in safe environments
We believe that safe products can only be made in safe working environments. Just as we design our valves to be safe for you to install, service and operate, we pay careful attention to the safety of our own production processes.
Still setting the standard for soft-seated butterfly valves
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.
The butterfly valve for any given situation
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.
