History and Philosophy

1954

Foundation of the Max von Rohr AG in Muttenz. Manufacturing and distribution of pneumatic driven valves. Over the years, the production of valves has been expanded to pneumatic control circuits up to the automation, which included complete cabinets with the programming logic, switching elements and writers for the process industry.
