    • A control valve comprises a valve body (1) including two flow channels (2, 2'); a cup-formed, steplessly turnable closure member (5); and a shaft (6) for turning the closure member. On the sides of the closure member there is at least one opening (14). The second flow channel (2') has in the valve body (1) an extension (10), the outer surface of which forms a surface of revolution concentric with the inner surface of the closure member (5), and which extends within the closure member. On the sides of the flow channel extension there is at least one opening (21). The opening or openings (14) of the closure member are located so that in the open position of the valve they at least partly overlap the opening or openings (21) of the flow channel extension (10). In the closed position of the valve the openings of the flow channel are covered by the closure member.
