Abstract: 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).

Abstract: A valve cage (100) for a control valve (10) incorporates a plurality of throttle channels (104) which extend from an inner contour of the valve cage (100) to its outer contour and penetrate the valve cage (100), each throttle channel (104) having an inlet opening (106) on the inner contour side and an outlet opening (110) on the outer contour side when viewed in the flow direction (S). When viewed in the circumferential direction (u), the valve cage (100) has a plurality of arcuate outer contour portions (112) which are each separated from one another via a step (114) acting as a tear-off edge, and the throttle channels (104) are arranged so that they extend such that the outlet openings (110) of the throttle channels (104) on the outer contour side are arranged in the step (114) between two outer contour portions (112).
