Engineering for the highest demands and greatestburdens

For more than 25 years, RBU has been your specialist for process engineering design as well as the manufacture and assembly of process and thermal engineering components and systems from a wide range of industrial sectors. We are proud of our products and proud of our reputation: Where others give up after a short time, our systems still work reliably and precisely after many years. Many years of experience and state-of-the-art engineering know-how ensure that our products and solutions function reliably and smoothly even under the most adverse conditions - whether in extreme heat or under the influence of corrosive media and aggressive dust. We deliver customised solutions for every application - because perfect engineering is our passion.



We score not only with the outstanding quality of our products, but also with individual industrial system solutions that are always designed and createdin close cooperation with our customers. Our many years of experience in engineering, manufacturing and assembly, as well as the outstanding expertise of our competent employees,help us to achieve this.

Complete support

By bundling competences through the merger of RBU, HBS and ME-Metall, we offer you comprehensive support in all areas. From technical planning to production and installation. Our trainedemployees ensure maximum quality and safety. - This means that you areideally equipped forIndustry 4.0.



With us, you as a customer are the focus. And that from the very beginning. From the initial consultation, through intensive project planning, to the final implementation, we always ensure transparency and optimal care through our support. Even long after the purchase of our products, we are there to help you with any problems or other concerns.

We write service in capital letters - worldwide and from the very beginning!

At RBU, service starts from the very beginning - in-depth, detailed and competent advice is provided at the start of every project. Individual industrial system solutions tailored to the respective process are just as much a part of our understanding of service as a cooperative partnership throughout the entire project. Because only in this way can we guarantee the best possible result for you in the end.

Our service allows you to fully concentrate on your core business. We adapt our solutions constructively to existing piping systems and realise the complete implementation from a single source with our qualified installation team. This saves time and money. Two incredibly important resources in every conceivable area.

We understand every task, no matter how unusual the application, as a challenge and apply our know-how with the greatest flexibility and in close dialogue with our customers in the sense of individual, efficient and durable solutions. Numerous satisfied customers all over the world - from innovative small businesses to renowned large companies - are our incentive and confirmation. Our service does not end with the delivery, as we take over the assembly or the assembly management and initial operation if required and ensure maximum availability through further support during the long-lasting use of our components and systems.

What can we do for you?

For over 25 years, customers have valued our manufacturer-independent advice, our industry-specific know-how and our high-quality special solutions in a wide range of industrial sectors. The most common fields of application include:

We offer industrial system solutions not only in Germany, but wherever intelligent engineering and reliable shut-off and control systems are required, even for the most unusual applications. Accordingly, we provide efficient and individual concepts and solutions of the greatest precision and the greatest durability worldwide to help you quickly and reliably.

In 2015, for example, we sold several safety flaps (SIK) to the Mitsubishi Heavy Industries shipyard in Nagasaki, Japan. There they were used to build the cruise ships AIDAprima and AIDAperla. As a service provider, we were of course personally on site in Nagasaki in 2015 and commissioned the flaps there together with the customer. You too can benefit from our reliable work and comprehensive range of services around the globe.

But since creativity never comes off the peg, we also offer individual system solutions for special applications of all kinds.

RBU shut-off and control valves are central elements for optimising processes and increasing energy efficiency - disturbance variables are safely compensated and constant process parameters are guaranteed even under the most extreme environmental conditions. For every application, we offer efficient and customised solutions of the greatest precision and durability.

  • Air and hot gas fittings
  • Control dampers as multistage multileaf dampers
  • Double wing dampers (tandem) with sealing air (according to TRD)
  • Diverter (gas diverters)
  • Gate valves for gases and flowable solids
  • Safety flaps
  • Steering arm flaps
  • Spectacle slider
  • Pendulum locks
  • Conversion of old valves, e.g. manual gate valves to automatic operation
