1. A control valve (1) for at least one sanitary fitting, comprising at least:
a body (2) having at least one inlet (3) for a liquid;
a diaphragm valve (4) for opening and closing a flow channel (5) of the control valve (1), wherein the diaphragm valve (4) has a diaphragm (6) and a counterpressure chamber (7) connected to the at least one inlet (3), and wherein a pilot orifice (8) is formed in the diaphragm (6), which pilot orifice connects the counterpressure chamber (7) to the flow channel (5);
a multi-port valve (9) disposed downstream of the diaphragm valve (4) and having a plurality of outlets (10, 11) for the liquid; and
a controller (12) for controlling the diaphragm valve (4) and the multiport valve (9), wherein the controller (12) comprises a control rod (13) extending through the pilot orifice (8) of the diaphragm (6), wherein the control rod (13) can be adjusted in a longitudinal direction (14) for controlling the diaphragm valve (4) and can be rotated for controlling the multiport valve (9).
