The fitting has a valve (18) for cold water and a valve for (sic) (20) for hot water. Arranged fixedly on the closure part (38) interacting with the valve seat (42) is the auxiliary valve seat (56) of the relevant auxiliary valve (52, 54). The closure element (58) can be displaced in the direction of the axis (30) from the idle position shown into the desired limiting position by displacement of the control pin (82) in the direction of the axis (78′) and by rotation of the same about the axis (78′). The auxiliary valves (52, 54) are thereby opened which leads to a pressure drop in the pilot control space (40). The closure parts (38) are lifted from the valve seats (42), by which means the water can flow from the inlet (22, 22′) into the outlet (48, 48′). When the valve (18, 29) is opened, the gap between the O-ring (66) and the auxiliary valve seat (56) thus becomes smaller. This results in a pressure balancing occurring between the pilot control space (40) and the other side of the closure part (38). The quantity of water flowing through a valve (18, 20) is thus determined by the limiting position of the closure element (58). The fitting thus no longer requires a mixing valve, the temperature of the mixed water flowing out through the water outlet head (28) is determined by the quantity of cold and hot water released by the valves (18, 20).

A sanitary fitting having at least one hydraulically operable valve arranged between an inlet and an outlet for releasable blocking of a flow of water through the fitting, the hydraulic control circuit of which valve is connected to the inlet and the outlet and has an auxiliary valve with an auxiliary valve seat which is movable together with the closure part of the valve and a closure element interacting with said auxiliary valve seat, it being possible for the closure element of the auxiliary valve to be brought by means of a drive arrangement out of an idle or rest position, in which it rests on the auxiliary valve seat when the valve is closed, for opening the valve into an open position, in which it is lifted from the auxiliary valve seat when the valve is open, and to be brought to rest on said auxiliary valve seat again for closing the valve and to be moved back into the idle position resting on said auxiliary valve seat, wherein the closure part (38) is of diaphragm-shaped or piston-shaped construction and interacts with a valve seat (42) arranged on the one side of the closure part (38), wherein, on the other side, a pilot control space (40) is provided which is connected to the inlet (22, 22′) and can be connected via the auxiliary valve (52, 54) to the outlet (48, 48′) and separated from the latter, in which pilot control space there is arranged the closure element (58) interacting with the auxiliary valve seat (56) arranged on the closure part (38) and in effective connection by means of a transmission member (64) with a drive part (111) of the drive arrangement (71), wherein the closure part (38) has a control passage (60′) which is connected to the outlet (48, 48′) and bounded by the auxiliary valve (52, 54) on the pilot control space side, wherein the transmission member (64) is passed through the control passage (60′), and wherein the valve seat (42) is of annular construction and bounds an outflow path connected to the outlet (48, 48′), the wall of which outflow path has in the region of this end of the transmission member (64) a diaphragm-shaped wall part (50) which can be deflected to actuate the auxiliary valve (52, 54) from the side opposite the transmission member (64) acting on the latter.
