Neles butterfly valves deliver versatility and performance for severe service applications
Their compact and lightweight design, availability in larger sizes and easy usability make Neles 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.
Versatility through smart design
One industrial sector where Neles™ butterfly valves continue to prove themselves is the refining and petrochemical industry. As in many industrial segments, there too, the requirements placed on valves are becoming increasingly tight. To ensure we stay ahead of evolving customer demands, we have released our most versatile and advanced butterfly valves to date.
Maintaining excellent long-lasting tightness over the valves entire service life is one key requirement for valves in on-off and emergency shutdown service.
Maintaining excellent long-lasting tightness over the valves entire service life is one key requirement for valves in on-off and emergency shutdown service. Safety is a high priority for Neles butterfly valves such as the new Neldisc™, which offers true metal-to-metal sealing with virtually zero leakage. Our butterfly valves are SIL 3 capable for reliable performance in ESD service.
When it comes to using butterfly valves in control valve service, we now offer customers two different shaft options – Drive shaft with trunnion providing high flow rates and a robust through-shaft option for both Neldisc™ (triple offset) metal-seated valves and Wafer-Sphere™ (double offset) soft-seated valves. This is a particularly useful feature for control valves, especially in cases where higher Cv is required for a particular size.
Optimized performance for severe services
The vast majority of valves and valve applications in any industrial process could be classed as standard. Yet in all process units there are some valve applications that are considered challenging. For example, when valves need to handle oxygen, high cycling, dirty media, corrosive media or cryogenic temperatures. Neles butterfly valves have the answers for such challenging and severe service requirements.
Valves in refinery and petrochemical industry service typically need to handle very high temperature liquid flow media. For example, in processes such as hydrotreating, reforming or cracking, and when handling utilities like medium- and high-pressure steam.
Our metal-seated Neldisc butterfly valve is suited for high temperatures and has the capability to handle dirty media. Our true metal-to-metal seal has no graphite, which is known to flake and be unable to withstand higher temperatures. Our metal-seated butterfly valves also come equipped with a high cycle construction. Also, the Neldisc’s soft-seated twin brother, the Wafer-Sphere, may be the right choice for some demanding, high cycling applications.
Keeping sustainability in mind
We design and manufacture the world’s most versatile butterfly valves, which have been designed with three types of performance in mind; process performance, environmental performance and economical performance.
When talking about sustainability and safety in industry, the topic quickly turns to emissions. Emissions have gained more and more attention and continue to be a literal hot topic as we discuss the threats of climate change. Eliminating leakages and fugitive emissions through the valve body has become more or less a mandatory feature for any top-of-the-line process valve. Neles butterfly valves comply with ISO 15848, which is the widely accepted emissions standard in industry.
The other key areas where the best valves can make a difference is in helping optimize process efficiency and energy consumption. We design and manufacture the world’s most versatile butterfly valves, which have been designed with three types of performance in mind; process performance, environmental performance and economical performance.
Versatility can also mean simplicity and ease
With our new butterfly valve offering we are providing customers one single technology platform that covers a wide range of process needs with benefits such as a simplified offering, improved availability and lead times, reduced variance, interchangeability of parts, late configuration with add-ons and a simplified spare parts strategy for more efficient operations.
The Neldisc and Wafer-Sphere valves have both been considered the industry benchmark in their respective fields for decades. But we have always been, and still are, committed to continuously developing our offering to meet and exceed the needs and expectations of a rapidly evolving world and industrial landscape.

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, VP, Butterfly valves product center at Valmet.
Next generation versatile butterfly valves
The new generation of Neldisc™ metal-seated and Wafer-Sphere™ soft-seated butterfly valves is built to deliver sustainable performance today and tomorrow. Our versatile product range includes both metal-seated butterfly valves and soft-seated butterfly valves.
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.
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, Senior Research Engineer, about the design process behind the new modular butterfly valve platform.
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 in 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 Neldisc™ metal-seated and 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 Neles 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 Neldisc™ and soft-seated Wafer-Sphere™ valves, have been designed and developed over time to address today’s needs and challenges.
