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).
