A shut-off valve for a tank, including a filling tube with a filling-side valve seat and a tank-side valve seat. The seats being spaced apart from one another in a throughflow direction of the filling tube. A valve body with a sealing element is movable between the valve seats so as to butt against one of the valve seats depending on position of the valve body in the tube. A component is provided for prestressing the valve body toward the filling-side valve seat so as to seal the filling tube in relation to the filling-side valve seat in a rest position of the valve body, the prestressing component being configured so that the prestressing of the valve body can be overcome by flow pressure of a medium which is to be introduced toward the tank-side valve seat. A filling-level-controlled stop device is operatively arranged for stopping movement of the valve body in the direction of the tank-side valve seat in a position in which the sealing element is kept at a distance from the valve seats so that the medium which is to be introduced can flow around the valve body. The stop action of the stop device is eliminated when a predetermined filling level in the tank is reached.
