An idea conquers the world.

Until 1960, Gottfried Müller († 1990) worked at Hornschuch AG in Weissbach. At his parents’ “wine tavern” in Stuttgart, he came into contact with employees from what was formerly known as Daimler-Benz AG. They spoke of problems with the valves in the supply of coolant: They were too slow, too unreliable, and too prone to failure in order to keep up with the ever growing pressure in system technology. Although Gottfried Müller, as a Chemical Technician, had never had anything to do with valves, he worked intensively on a solution. And he actually came up with an idea! He let the idea ripen and came up with a name for his invention (“coaxiality”) – the technical term for when two round bodies lie on the same axis. In 1970, his coaxial valves were presented for the first time at the Hannover Trade Fair. It was a technical revolution!
