Abstract

The invention relates to a check valve for blocking a fluid-carrying line in case of reversal of the flow direction, containing a valve housing defining a flow path and having two connecting pieces and a valve seat therebetween, and a flap module mounted in the valve housing and containing a shut-off body interacting with the valve seat, a bearing device for pivotably supporting the shut-off body such that the latter is movable between an open position and a closed position, and a lever extending between the shut-off body and the bearing device and being connected to the shut-off body and the bearing device. For easier manufacturing, the invention proposes that a part of the flap module is formed by at least one sheet-metal shaped part.
