The invention relates to a control cone for control valves, in particular angle control valves, for critical operating states resulting from cavitation or flashing of abruptly vaporizing and erosive media, the control valve comprising a valve seat (2) and a valve stem (3) with a conical valve head (4) guided longitudinally movably therein. Starting from the rear, tapered end of the conical face (6) of the valve head (4), on the front portion adjacent thereto of the valve stem (3), a plurality of coaxially extending ribs (5) is arranged on the valve stem (3).
