The invention relates to a control valve (10) for a process plant, comprising an actuator (16) which is connected to, and spaced from, a valve body (12) of a valve unit (11) via a yoke (14), the valve body (12) having a housing flange (32) which is detachably connected to the yoke (14), with the valve body (12) having an inlet (20) and an outlet (22) adapted to allow the flow of a process fluid therethrough, which inlet (20) and outlet (22) are each arranged in a fluid connection region (18, 19), and with an actuating member adapted to be displaced by the actuator (16) for controlling the flow rate of the process fluid being arranged in the passage (24) from the inlet (20) to the outlet (22). The invention is characterized in that the housing flange (32) connected to the yoke (14) has at least one recess (44) as well as a yoke fastening region (33), with the yoke fastening region (33) being formed as a bolt hole circle (34) with radially arranged connecting holes (36).
