Abstract: A valve (1) for a sanitary faucet, comprising: a liquid duct (2) having at least one inlet (3) and at least one outlet (4) for a liquid; a diaphragm valve (5) having a diaphragm (6) and a counterpressure chamber (7) connected to the at least one inlet (3); and a control rod (8) for controlling the diaphragm valve (5), wherein a push button (9) can be used to adjust the control rod (8) between a closed position, in which the diaphragm valve (5) is closed, and an open position (10), in which the diaphragm valve (5) is at least partially open, wherein a rotary handle (11) can be used to adjust the control rod (8) in the open position (10) between a minimum flow position (12), in which a minimum flow rate of the liquid flows through the at least one outlet (4), and a maximum flow position (13), in which a maximum flow rate of the liquid flows through the at least one outlet (4), and wherein the minimum flow position (12) of the control rod (8) can be variably adjusted.

Abstract: A control valve for at least one sanitary fitting that contains a body having at least one inlet (3) for a liquid; a diaphragm valve for opening and closing a flow channel of the control valve, the diaphragm valve having a diaphragm and a counterpressure chamber connected to the at least one inlet, and a pilot orifice being formed in the diaphragm, which pilot orifice connects the counterpressure chamber to the flow channel; a multi-port valve disposed downstream of the diaphragm valve and having a plurality of outlets for the liquid; and a controller for controlling the diaphragm valve and the multiport valve, the controller containing a control rod extending through the pilot orifice of the diaphragm, wherein the control rod can be adjusted in a longitudinal direction for controlling the diaphragm valve and can be rotated for controlling the multiport valve.
