Quality for Three Generations

Tradition & Innovation

Starting as a small engineering office in the post-war period, Hartmann Valves has grown into a globally active system provider with 230 employees and has been family-owned for three generations.

The keys to success, then as now, are innovative product developments: from the first ball valve patents to customized high-performance valves and wellheads for demanding conditions. On January 1, 2018, brothers Werner, Christian, and Martin Hartmann took over the management of Hartmann Valves GmbH.

The three brothers Martin, Werner, and Christian Hartmann (from left to right) lead the family business in the third generation.
