Samson AG

Samson AG initially gained recognition for inventing a self-operated thermostat valve that regulated temperature in grain silos without external power in 1907. By 1916, Samson AG had relocated its main manufacturing facility and headquarters to Frankfurt’s River Main. Over the years, the company expanded its product line to include control valves, self-operated regulators, actuators, and automation systems. Significant milestones include the introduction of the first pneumatic control valves in the 1950s, expansion into digital control systems in the 1980s, and the formation of a joint venture with Krohne Messtechnik in 2019.
