Abstract: A valve cartridge for a sanitary fitting having a cartridge housing, a valve stem which is rotatable about an axis of rotation relative to the cartridge housing, a handle for rotating the valve stem, a passage disk with a first passage and a second passage, a control disk rotatable with the valve stem for controlling a liquid flow through the first passage or the second passage of the passage disk, a handle adapter which can be connected to the valve stem for setting a first rotational orientation of the valve stem to the handle in a first position and can be connected to the valve stem for setting a second rotational orientation of the valve stem to the handle in a second position, so that the control of the flow of liquid through the first passage or the second passage can be changed by the control disk.

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.
