Zusammenfassung:	A valve device for a fuel cell arrangement in a motor vehicle includes: a housing; a flow duct extending in the housing; a shaft mounted rotatably in the housing; a flap configured to influence the flow cross section of the flow duct, wherein the flap is arranged on the shaft, and coupled to an electric motor and a gear mechanism; a valve seat arranged in the flow duct; and a seal arranged on a radially encircling edge of the flap such that the seal is in contact with the valve seat when the flap is in a closed position, and such that the shaft penetrates the flap at an angle. The shaft with the flap arranged thereon is movable by the electric motor only via the gear mechanism and movement of the flap is blocked in all other cases due to a frictional force generated by the seal.
