From innovative idea to order in six months

The requirements of the modern industrial gases market are continuously getting tougher when it comes to product safety, quality and compliance with all necessary certification criteria. For The Linde Group, the world’s largest industrial and medical gases company headquartered in Munich, Germany, as well as for its main suppliers, this calls for constant development to stay in a leading position.


When the need for a new valve solution arose, the company began to look for a partner who would be able to help Linde step up to the more stringent requirements and succeed in its changing environment.

Successful cooperation history was one of the factors that played in favor of Neles when the company was selected to develop an innovative cryogenic valve required for Linde’s new air separation unit (ASU) in Eisenhüttenstadt, Germany in a very short time period.

Tight time constraints

Time-to-market was a considerable issue for Linde. Thanks to the fast reaction ability and high level of professionalism of the teams, the whole process went smoothly. The intensive joint research and development phase resulted in the fast approval of the new BWX valve.

The close collaboration during the design phase ensured that the end product is 100% compliant with all of Linde’s requirements. And the first order for the cutting-edge valve was placed only six months after the initial idea was born.

Filling the gap

There was a clear gap in the industrial gases sector when it comes to products with extremely high tightness that fit the challenging cryogenic and oxygen services. To create a state-of-the-art valve that would be capable to fill this gap, the best design features of an existing product series were combined.

BWX is the latest valve development from Neles. Its metal-to-metal seated butterfly design provides a unique body and high Cv values. The valve is based on a platform design, which ensures high customization. Thanks to its fully dry assembly and oil-free production, the valve is ideal for this demanding application, as it requires an extreme level of tightness. Most importantly, BWX meets Linde’s new oxygen service requirement. This is key, as the ASU’s main purpose is to serve oxygen and nitrogen to the local steel manufacturing facility.

Beyond valves’ standard role

BWX not only answers to Linde’s technical needs, it also offers value for customers in the industrial gases sector as well as pump and turbine businesses by allowing them to fulfill stricter compliance regulations in the future. 

For Linde, the value from having BWX valves at its air separation facility comes with increased safety, improved process performance and assurance of the plant’s compliance with the latest safety and quality standards. All valves play an important role in ensuring the plant’s reliable and efficient operations over the long run, yet BWX goes beyond that with the ultimate goal to secure the technical and commercial competitiveness of the company.
