An exhaust-gas recirculation (EGR) valve includes a rotary drive. The rotary drive includes a cam member that has a cam profile. The rotary drive permits operation of a valve member that can be rotated around a rotational shaft. During the course of a closing movement, the EGR valve can, toward the end of the closing movement, move towards a valve seat in a direction that is generally parallel to a direction of flow through the valve seat.
