Müller slide
The Müller valve is a pressure equalizing piston valve for steam locomotives . It was developed as a further development of the Karl Schultz gate valve in the period after 1945 and was the standard design of gate valves on steam locomotives of the Deutsche Bundesbahn .
Just like the Karl Schultz gate valves, the Müller gate valves consist of four piston elements per piston rod. The two piston ends at the rod ends are firmly attached to the rod. In contrast to the aforementioned pressure compensation piston valve, the pressure compensation is provided by a pressure compensation valve located in each piston half. The closing of the pressure equalization valves takes place from a certain valve chest pressure. In the literature, these pressure compensation valves are described as being susceptible to large diameters, but they have proven themselves well in the reconstruction of the 01 series locomotives.
