While the majority of the butterfly valves in the market meet key industry standards (API, ASME, EN) and regulations, the real difference can always be found in the design. When looking for reliable, long-lasting performance the optimized triple offset design found in our modular butterfly valves really stands apart. The design itself is based on decades of experience and the utilization of the latest developments in manufacturing technologies.
The triple offset design, as well as many of the other smart design choices, have been meticulously engineered, developed and refined to deliver the best possible performance. In terms of the unique seat design, it provides industry-leading tightness even at high pressures. And what has perhaps been most important about this torque utilizing position seated design is that true tightness is achieved with a considerably lower torque requirement. A lowered torque requirement reduces wear and improves longevity, but it also helps improve the energy efficiency of valves with a reduction in need for pressured air. It may even allow you to size down on the actuator in use.

The combination of lower torque, accurate seat design and carefully selected low-friction materials act together to reduce wear and tear, providing long-lasting performance. The benefits of the true modularity of the design come into play when service and maintenance is required. It doesn’t happen often, but when it does, it’s faster, cheaper and easier. All wear parts are easy to remove and replace. There is no welding required. Where in other cases you might need to replace an entire valve, with this smart design, you only need to change out a part or two. Also, the fact that the modular parts have compatibility across the entire modular butterfly valve range means that on-site spear parts inventory is significantly simplified.
Extensive testing ensures reliability and long-term performance
Long-lasting performance is not only something we talk about, it is something we prove through extensive testing. In addition to testing valves prior to shipping for tightness and temperature- and pressure-ranges, type testing is increasing in popularity. Type testing is a great way to verify to the customer the long-term performance of valves by running an exemplary valve through a high-cycle test period that equates to a longer time in operation.
We at Neles take great pride in being able to deliver the type of long-lasting reliability we talk about. Our modular butterfly platform is a testament to how ambitious design and engineering paired with high-quality manufacturing and material selection can truly help us deliver on our promise and deliver performance that sets us apart from the competition.
