High-performance valves
Jamesbury™ brand valves have always been recognized leaders in valve technology. For more than 65 years, our unique features have been field-proven to provide trouble-freeshut-off in thousands of applications just like yours. This experience allows us to provide a butterfly valve that can lower your costs without risking performance.
Why Jamesbury high-performance valves?
Our high-performance valves combine a number of seat designs and revolutionary Xtreme™ sealing technology to provide you with the tightest-sealing, longest-lasting, lowest-cost alternative to gate valves, as well as to other heavier, rotary-type valves. Wafer-Sphere™ high-performance butterfly valve's life is far greater than a traditional butterfly valve, they are often a more cost-effective solution even for applications without high-performance service demands.
Jamesbury valves are suited for applications in pulp & paper, grain/corn processing, chemicals, petrochemicals, power, refining, steel, air separation, HVAC and more.

Jamesbury™ ball valves
When it comes to ball valves, we know your most important consideration is reliability. The longer a valve performs as designed and without problems, the better. That’s why your choice should be Jamesbury ball valves. By focusing on the all-important areas of seat design, polymer material research and sealing technologies – we were able to engineer and deliver next generation ball valve performance. Solutions that offer you vastly improved stem sealing and cycle life. In fact, depending on the application, the cycle life of these new valves can be as much as 100 times greater than the cycle life of competitive products.

Jamesbury butterfly valves
The combination of a unique off-center disc, proprietary seat design, Xtreme™ sealing technology, and other features make our Wafer-Sphere™ high-performance butterfly valve a tight-sealing, long-lasting, yet lighter and lower-cost alternative to gate valves and other heavier rotary-type designs.

Valve services

Valve maintenance and repairs
All valves must be repaired at some point. Incorrect repairs or the use of inferior parts create safety risks. That’s why being your reliability partner means we carefully plan maintenance and only use original spare parts to reduce the number of unexpected production breaks and failures. Quality repairs using original spare parts ensure that your valves meet their original specifications after maintenance and will reach their maximum lifetime.

Plant maintenance and lifecycle services
A single equipment failure can cost thousands in lost production. We can help you to prevent these failures and keep your plant running at its full capacity. Well-designed maintenance planning and effective service execution ensure the safety and availability of your field devices and reduce downtime.

Parts for valves
Neles™ spare parts meet the original material and specification requirements of the valve assembly initially purchased. The use of genuine parts ensures that they are specifically suited for your industrial process, and their certificates remain legitimate. Your valves perform as intended, reaching their maximum lifetime.
