A new generation packed with performance
Product Manager, Butterfly Valves
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.
Safety and reliability
The modular nature of the valve construction with three body types, two shaft options and two seat options, allows for up to 12 unique valve configurations. Regardless of valve type and configuration, one thing always holds true: Safety. All of the valve designs take into careful consideration factors such as fugitive emissions, fire safety, PED and blowout proofing. Each valve is constructed using the best possible materials for a wide range of demanding applications.
Key industry standards such as API, ASME and EN have always been driving design principles behind these high-performance valves. Whether you are using our triple eccentric metal-seated valves or double offset soft-seated valves, all configurations are suited for use in both key pressure classes, ASME 150 and ASME 300 (PN10-PN40) in terms of valve construction and flange drillings. With the new modular platform, our range now also includes a soft-seated valve with double flanged body. The strong disc and robust design of the lug and double flanged valves also make them an ideal solution for effective dead-end service.
As sustainability continues to be an important factor in valve selection, reducing the possibility of external leakages and fugitive emissions is particularly important. Eliminating possible leakage paths in the valve packing and body joints has been a high priority in the design of our butterfly valves. The disc and seat design has been further optimized to ensure long-lasting tight shutoff and low emissions across the entire product family, in both metal- and soft-seated configurations.
The ability to achieve the highest flow capacity available on the market today with both the drive shaft and the trunnion shaft design helps increase overall plant efficiency considerably. Also, the robust valve construction and easy serviceability helps extend the lifecycle of our valves, reducing downtime and allowing you to make the most of your valves in daily operation.
The modular valve platform paired with the fact that our valves are equally suited for both control and on/off service, means that reliability is improved while the need for on-site spare parts inventory is reduced. The same valve components are suited for use in a vast array of service operations and can also be used to configure and assemble replacement valves locally to speed up the process.
The field-proven fundamental designs for our metal- and soft-seated butterfly valves have stayed largely unchanged over time. At the same time improvements are continuously being made to ensure that our tried and tested Neldisc and Wafer-Sphere valves continue to meet ever changing and tightening requirements. Each improvement, however small, is always thoroughly tested and implemented with the needs of our customers and their processes in mind.
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 Neles.
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.
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.
Neles as a company has a strong history when it comes to valve solutions for the pulp & paper industry. Like many other valves over the years, the Neles™ Neldisc butterfly valve was originally born in the 1970s to specifically serve in pulp and paper mills. Its strong performance gave it a universal appeal beyond just pulp & paper. Today, after undergoing much development, it is still a go-to valve for the rapidly evolving pulp, paper and bioproducts industry.
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.
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.
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.
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.
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.
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.
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 by Neles, 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.
