New generation of butterfly valves

Versatility and reliable performance have been driving forces behind the design of our new generation of butterfly valves. Also, the role of sustainability in industry, business and society at large has been a key factor in the development of these products. The engineering behind these valves also brings a new level ease and speed into installation, maintenance and spare parts handling. Find out what makes the new Neldisc and Wafer-Sphere the butterfly valve for any given situation.

It is no surprise that the versatile valves of today are engineered and built to set the standard for modern butterfly valves in the service of a wide range of industries. Today’s technology has its roots on two different continents, reaching as far back as 45 years. Read the article '45 years of butterfly valve expertise' to find out where it all started. Many new features have been introduced over the years, but the fundamental design is still the same today as it was back then. After all these years and several new developments, find out why the Wafer-Sphere is still considered the standard for soft-seated butterfly valves today.

The new generation of Neldisc and Wafer-Sphere butterfly valves are based on the same platform, sharing many design features, modular components and tangible customer benefits. The highest Cv on the market, paired with the low torque requirement make for excellent energy efficiency. The valve design that minimizes fugitive emissions further improves energy efficiency, process yield and overall sustainability. This is what the future of efficient, reliable and sustainable butterfly valves looks like.

The new generation of Neldisc and Wafer-Sphere butterfly valves have been engineered and manufactured with sustainability in mind. The compact design ensures the best possible efficiency while using as little raw materials as possible. The valves help reduce fugitive CO₂ and other greenhouse gas emissions while delivering the best possible energy efficiency thanks to clever innovations and the latest in manufacturing technologies.

Sustainable, yet profitable performance is a result of design and engineering aimed at minimized emissions and reduced size, weight and complexity.

The butterfly valve portfolio lead by its flagship valves – Neldisc™ and Wafer-Sphere™ – offers sustainable process performance. Sustainable, yet profitable performance is a result of design and engineering aimed at minimized emissions and reduced size, weight and complexity. Our reliable valves are designed to deliver long-lasting consistent performance with longer maintenance intervals and fewer shutdowns over the extended valve lifecycle.

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.

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.

Safer butterfly valves are made in safe environments

Jun 21, 2021

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.

The modular design of our valves makes parts replacement and service operations safer, faster and easier. It also means that maintaining spare parts inventory on site is further simplified and optimized when using our Neldisc metal-seated or Wafer-Sphere soft-seated butterfly valves. The savings start stacking up when you can replace individual parts or components rather than entire valves. Our industry-leading butterfly valves offer lower energy consumption and improved process efficiency. Learn more from the video interview with Taija Hämäläinen, Director, Butterfly Valves Product Line at Valmet.

Service is a key benefit of the product itself

Dec 14, 2021

Neles butterfly valves are a trusted part of many industrial processes the world over. There are currently more than a quarter of a million butterfly valves installed around the globe. And this number only includes the valves in our installed base database. In addition to the products themselves our service expertise is often a key reason behind many clients selecting our butterfly valves.

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.

Sustainability and process efficiency often go hand in hand. In this case all of the reductions in size, weight, complexity and subsequent energy consumption directly translate into both improved environmental performance and increased process efficiency. By enabling improvements in business performance while meeting ever-stricter environmental regulations, these valves are ushering in the future of better industrial processes.

Designed to eliminate fugitive emissions, our butterfly valves eliminate the leakage of CO₂ and other potential greenhouse gasses into the process area and the general atmosphere. This improves both work safety and environmental performance. Also, when you are not losing valuable flow media and pressure through fugitive emissions you are improving your process yield and energy efficiency.

High quality and robust design reflect on valve’s reliability and performance. We interviewed Tommi Bergström, Manager, Engineering Analysis, about the design process behind the new modular butterfly valve platform.

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.

Modularity as a concept allows a high level of standardization while also enabling flexibility so that it can provide the perfect solution for each process. The basic principle of the platform is that we always have a standard valve as a base, so the basic features are there. You can then make decisions based on the needs for your process. With the different choices you can configure multiple solutions to best suit your needs – this is true modularity.
