A control valve, in particular a proportional valve for controlling a device for adjusting the rotation angle position of a camshaft with respect to a crankshaft of an internal combustion engine, including a hollow-cylindrical valve housing (1), which has a plurality of openings (2) that are arranged circumferentially in a radial plane for connecting to a pressure medium connection (P) and can be closed via a non-return valve (4) designed as a curved spring band (3). According to the invention, the openings (2) arranged in a radial plane are arranged at different angle distances to each other, and the shape and the rotation angle position of the curved spring band (3) serving as a non-return valve (4) is matched thereto.
