DIAM & DDM Bochum

12. - 13. November 2025 | German trade fair for industrial valves and sealing technology

The DIAM & DDM, a trade fair in Germany, focuses specifically on the area of industrial valves and sealing technology. The abbreviation "DIAM" stands for "Deutsche Industriearmaturen Messe" (German Industrial Valve Fair), and "DDM" stands for "Deutsche Dichtungsmesse" (German Sealing Fair). This event takes place biennially in Bochum and was established to provide a central forum for professionals, manufacturers, and users in the industrial valve sector. Organized by MT – Messe & Event GmbH, this event regularly attracts industry insiders seeking the latest innovations and proven solutions in these specialized technical fields..

Since its inception, DIAM & DDM has made a name for itself through its unique focus on the practical applications of valves and related technologies. The emphasis is on those who work with these products daily, providing a platform for dialogue, further education, and the presentation of optimization solutions and advanced technologies.

A key feature of the fair is its diverse supporting program. In addition to the exhibition itself, highly interesting technical presentations and hands-on workshops enrich the offerings. These sessions, led by leading experts in the field, provide insights into current trends, promote the exchange of best practices, and discuss ways to further develop existing applications and techniques.

A highlight of the fair is undoubtedly its unique location – the Jahrhunderthalle in Bochum. This historic industrial site underscores the long industrial tradition of the region and creates an atmospheric backdrop for the presentation and discussion of industrial valves and technologies. The visible handwheels, fittings, pumps, and cranes of the Jahrhunderthalle serve not only as a reminder of the site's industrial heritage but also as a vivid representation of the industry itself.

Products and services presented at DIAM & DDM cover a wide spectrum – from the latest types of industrial valves to innovative sealing and drive technologies, as well as accessories and technical services. The fair not only serves as a showcase for new products but also as a forum for technical support, networking, and business development.

Overall, DIAM & DDM offers a comprehensive industry experience. By combining exhibition, education, and networking opportunities, it provides invaluable added value for everyone involved in the relevant industrial sectors. In doing so, it sets a significant exclamation point in the region and in the industry as a whole.
