Patent attributes
A multiway control valve is provided having a housing that has an inlet connection and an outlet connection for a liquid and/or gaseous medium, a rotatably mounted ceramic valve disc, which is arranged with a first through-flow opening and rotatably mounted in the housing to fluidically connect and disconnect from each other the connections depending on its rotational position. The valve disc rests flatly on a ceramic sealing disc, arranged in a torque-proof manner and having two second through-flow openings, and a sealing element, which is arranged between the sealing disc and an intermediate floor of the housing and is elastically deformable. The sealing element has a disc shape and has third through-flow openings that are aligned with the second through-flow openings. The intermediate floor has at least one retaining projection that engages in one of the three through-flow openings for positively locking anti-twist protection of the sealing element.
