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 process medium-controlled regulating valve for a liquid throughflow regulator, having a main valve, a pilot valve for controlling a main valve piston, a pilot valve piston which closes the pressure relief line in a closed position, a cleaning wire element which is stationary in the axial direction is guided with hole tolerance through the pilot line, and the pilot line can be moved along the cleaning wire element, which is guided therein, during a stroke adjustment of the main valve piston. The cleaning wire element has an actuating contour which, at least during the stroke adjustment, can be brought into sliding contact with a counter-contour formed on the main valve piston, with the build-up of a transverse force which acts on the cleaning wire element.
