STÜBBE ball valves for electroplating processes

Tight space and tight schedule

50 different surface finishes of the highest quality are required, i.e. all surface variants used on the market, optionally in automotive quality: Bright and matt chrome, matt, bright and pearlescent nickel, (MPS nickel, MR nickel), copper as well as matt and bright gold.

This demand requires top-quality plating solutions. The plating solution basins are cleaned on a regularly scheduled basis in order to meet the high quality standards and minimize unplanned downtime. This means it is necessary to reliably prevent "seizing" of the valves during operation.

There were numerous requirements for the implementation of the project. Two key factors were the available construction space due to the structural conditions and the tight schedule. On the other hand, the valves had to have large nominal diameters and high Kv values in order to operate the system in an energy-efficient manner and with top performance. A central management of substance flows was required. This was only possible with short distances, compact valves and valve clusters.
