DIAM 2025
12th - 13th of November 2025
As a trade fair for industrial valves, drives, accessories and plant technology, DIAM is making a name for itself in the region.
In November 2025, the sixth edition of DIAM - German Industrial Valves Fair will take place in the "Jahrhunderthalle Bochum", the historic gas power plant of the Bochum Association. The two-day event offers exhibitors and visitors the opportunity to come into contact with one another in this historic location with a magical aura.
This networking idea includes both: the presentation of innovative high-tech products from the valves industry and the exchange of ideas, know-how and contacts. DIAM also offers you highly interesting specialist lectures and numerous workshops on the product on both days of the trade fair.
And all of this not in one of the usual anonymous exhibition halls, but in a venerable industrial monument in the pulsating heart of the Ruhr area. The majestic industrial cathedral “Jahrhunderthalle Bochum” is the ideal location for your industry, not only because of its history but also because of the large number of manufacturers, plant engineers, industrial suppliers and end users in its vicinity.
