Gottfried Müller developed the coaxial valve in 1960 and presented it a few years later at the Hannover Fair. This product triggered a development whose success continues to this day. Over the years, not only has the number of different types of valves increased, the number of employees at müller co-ax ag has risen as well. Today, the valve specialist offers more than 30,000 types of coaxial valves, high-pressure valves and custom valves that are manufactured, inspected, sold and supported by the company’s more than 160 members of staff. The products are used in various fittings, particularly in mechanical and plant engineering, the automotive industry, plastics, chemical raw materials and the gas industry. The company is represented by subsidiaries, sales offices and trade partners all over the world and is still in the process of expanding its network: the anniversary also marks the opening of our own Spanish subsidiary.
