| 1931 | Carl Kurt Walther founds the company in Wuppertal with the WALTHER-TROWAL division. It focuses on the manufacture and sale of machinery, systems and processes for surface finishing through vibration or slide grinding, which has become known globally as Trowalizing (TROWAL® = TROmmel WALther). |
| 1951 | WALTHER-PRÄZISION was founded during the 50s to meet the demands made by the company founder for a quick connector for the connection and disconnection of supply lines for a range of production machines manufactured by his company Carl Kurt Walther, Wuppertal.
Convinced of the technical and economic advantages, the first range of couplings was launched on the German market in 1951. Even back in those days, the couplings already satisfied the very highest quality requirements with many of these "first generation" products still working perfectly today. |

| 1996 | In the International Space Station, or ISS, Columbus, mono-couplings are supplied to cool the onboard equipment (Cooling System of Electrical Equipment). The European Science Laboratory docked with the International Space Station in February 2008. |
| 1997 | Development and delivery of mono-couplings for deep-sea use (depths of 3,000 metres), which prevent water from penetrating the hydraulic system, even when uncoupled. |
| 1999 | 6,000-bar high-pressure hydraulic couplings shorten fitting times when connecting the energy supply to forming dies used in series production. |
| 2000 | Head office and the overwhelming part of the production relocates from Wuppertal to the neighbouring Haan-Ost / Rheinland Industrial Park on the A46, with its good transport links, into buildings erected additionally. All jobs are retained. |
