Abstract: A valve for controlling the water flow in a sanitary line has a housing with a housing lower part in which a water supply channel portion, a control channel, and a water discharge channel portion are arranged in the flow direction. The control valve has a valve upper part with a head piece, which is arranged in a housing bore coaxially to the bore axis and to which a stator disc with a first ceramic surface is secured, and with a spindle, with which a rotor disc with a second ceramic surface is in engagement. The control valve also has an electric drive which is arranged in the housing upper part and which is in engagement with the spindle. Two seals which rest against the head piece and the spindle seal the control channel of the control valve from a housing upper part.
