AboutHartmann Valves GmbH

Hartmann Valves GmbH is one of the leading manufacturers of ball valves, pig valves and borehole flanges. Our references are global presence in the fields of oil, natural gas, petrochemicals, power plant technology, geothermal energy and other renewable energies. Design, assembly and testing are carried out exclusively in our plants in Celle and Burgdorf-Ehlershausen. We maintain an active dialogue with our customers, fulfill special requests and are considered a competent partner with our many years of experience.


Starting out as a small engineering office in the post-war period, Hartmann Valves has meanwhile grown into a global system provider with 200 employees and has been family-owned for three generations. Then as now, the key to success was the innovative product developments: from the first ball valve patents to tailor-made high-performance fittings and wellheads for demanding conditions. On January 1, 2018, the brothers Werner, Christian and Martin Hartmann took over the management of Hartmann Valves GmbH.
