The invention relates to a check valve with a tubular valve housing in which a valve ball is received. To make a large flow cross section available and to prevent closure by the valve ball when the check valve is fully open, a perforated disk is press-fitted between longitudinally extending guide ribs of the valve housing and a circumferential wall of the valve housing there is an interstice as an outflow opening, which is not closed even the valve ball contacts the perforated disk. The valve housing is made by stamping, in which the guide ribs and a valve seat are made in one operation and are thereby aligned exactly with one another. In this way, a small radial play of the valve ball can be realized.
