Abstract: A valve headpart (1) for a sanitary faucet (2), containing at least: a body (3), a valve stem (4), which is at least partially disposed in the body (3) and can be rotated relative to the body (3) about an axis of rotation (5), a seal (6) for at least partially closing a valve seat (7) of the sanitary faucet (2), wherein the seal (6) can be adjusted by the valve stem (4) parallel to the axis of rotation (5) between an open position and a closed position, wherein the seal (6) has a first sealing element (8) made of a first material and a second sealing element (9) made of a second material, and wherein a first hardness of the first material is lower than a second hardness of the second material. Moreover, a sanitary faucet (2) having such a valve headpart (1) is proposed.

Abstract: A single-lever cartridge for a sanitary faucet for adjusting the temperature and/or quantity of mixed water by means of a swivel lever (3), having a control disk arrangement (5), which has a stationary control disk (6) disposed in a stationary position in the cartridge, in which a cold-water inlet and a hot-water inlet (27, 29) and a mixed-water outlet (31) are formed, and a dynamic control disk (8) displaceable by means of the swivel lever (3), in which a recess (33) is formed, which is disposed in different overlaps with the cold-water inlets and hot-water inlets (29, 27) and the mixed-water outlet (31) to adjust the temperature and/or quantity of the mixed water fed from the mixed-water outlet (31) of the stationary control disk (6), wherein the two control disks (6, 8) are in sliding contact with sealing surfaces (35, 37) facing each other at a sealing plane (DE), and wherein the mouths (39) of the cold-water inlets and hot-water inlets (29, 27) are formed in the sealing surface (35) of the stationary control disk (6), which mouths can be covered by the sealing surface (37) of the dynamic control disk (8). According to the invention, the cartridge has a throttling element (41) designed as a separate component, which can be used to reduce a flow cross-section of the mouths (39) of the cold-water inlets and the hot-water inlets (29, 27), for throttling the hot-water flow and/or cold-water flow into the recess (33) of the dynamic control disk (37).

Abstract: A method for operating a sanitary fitting, and to a sanitary fitting. The sanitary fitting is equipped to deliver a water jet and has at least one manual actuator for manual regulation of at least one water jet flow rate or a water jet temperature, and a sensor arrangement that is equipped for sensor-controlled regulation of a predefined water jet flow rate and a predefined water jet temperature, wherein the sensor arrangement is equipped to detect the presence of an object in an external detection area and wherein a control unit is provided that is equipped to evaluate an object detected first and to distinguish whether the object detected first is a water jet or a different object. The present invention makes possible an economical production, the use of standard components, and low wear.
