Valve for sanitary fitting with diaphragm valve and adjustable control rod

The invention relates to a valve (1) for a sanitary fitting, comprising: a fluid guide structure (2) having at least one inlet (3) and at least one outlet (4) for a fluid; a diaphragm valve (5) having a diaphragm (6) and a back pressure chamber (7) connected to the at least one inlet (3); the invention relates to a diaphragm valve (5), comprising a handle (11) for rotating the diaphragm valve (5), and a control lever (8) for controlling the diaphragm valve (5), the control lever (8) being adjustable by means of a push button (9) 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 opened, the control lever (8) being adjustable in the open position (10) between a minimum flow position (12) and a maximum flow position (13) by rotating the handle (11). The control lever (8) has a minimum flow position in which the minimum flow of fluid flows through the at least one outlet (4) and a maximum flow position in which the
