  • Patent number: 10955058
    Abstract: A diverter valve for a sanitary fitting having a diverter valve housing, a valve body for the targeted supply of a fluid to at least two diverter valve outlets, and a spindle for actuating the valve body. The spindle is biased, so that after cutting the spindle to length, the spindle is displaced from the diverter valve housing by a defined travel. Also a concealed installation body with a corresponding diverter valve as well as a method for mounting a corresponding concealed installation body are provided.
