Butterfly Valves

When dealing with the control, regulation and monitoring of very different media, a riliable partner is required. Our innovations and know-how make us this reliable partner, as, after all, we developed the original coaxial valves.

Since 1960, coaxial valves made by müller co-ax ag are used everywhere where media has to be guided in a controlled manner, where quality without compromises is required and where the highest demands are placed on systems.

With the new valve series Quadax®, the müller co-ax group is expanding the range of products of valves, especially with larger sizes. The unique design, a quadruple (four offset) design and a new manufacturing technology, Quadax® meets the highest tightness requirements, even under extreme temperature conditions, ranging from -270 °C to +800 °C.
