Starting out as a small engineering office during the post-war period, Hartmann Valves has grown to become a globally active systems supplier with around 200 employees and has now been in family ownership for three generations. The key to success was then and still is the development of new products from the first ball valve patents to wellheads for demanding conditions and tailor-made high-performance valves for challenging media such as hydrogen and oxygen. This year the company celebrates its 75th birthday.

In a free interview with the German technical journal „Industriearmaturen“ the three managing directors and brothers Christian, Martin and Werner Hartmann reveal the contribution a medium sized family run company is making to the energy revolution with its products and what steps they are undertaking to this end.
