Abstract: A process medium-controlled regulating valve for a liquid throughflow regulator, having a main valve, a pilot valve for controlling a main valve piston, a pilot valve piston which closes the pressure relief line in a closed position, a cleaning wire element which is stationary in the axial direction is guided with hole tolerance through the pilot line, and the pilot line can be moved along the cleaning wire element, which is guided therein, during a stroke adjustment of the main valve piston. The cleaning wire element has an actuating contour which, at least during the stroke adjustment, can be brought into sliding contact with a counter-contour formed on the main valve piston, with the build-up of a transverse force which acts on the cleaning wire element.
