The invention relates to a fitting for switching over fluid paths, particularly for installations having pressure exchangers with tubular chambers (3), which are alternately flown through, whereby a rotating control element (10, 10.1) having a number of flow paths is mounted inside a housing (11). The housing (11) comprises a number of connections (12, 16, 17, 46) for connection lines, and is connected to a first pipe system and to an end of at least one pressure exchanger. Another end of a pressure exchanger is connected to a second pipe system with the interconnection of other fittings. The control element (10, 10.1) is provided with a motor-operated drive shaft (50), and the flow paths of the control element (10, 10.1) are alternately connected to openings inside the housing (11). A flowing to the control element (10, 10.1) ensues from an axial and/or radial direction, and a flowing way from the control element ensues in an axial direction. (FIG. – 3a)
