The invention relates to a control valve (10, 30) for adjusting a flow rate value of said control valve, comprising a valve housing (12) as well as a housing-mounted throttling structure (14, 34, 52) which covers a flow channel and includes at least two passages (16, 36, 54), furthermore a second closing structure (18, 40, 56) which can be moved relative to the housing-mounted throttling structure (14, 34, 52), which closing structure (18, 40, 56) can be moved so as to close the passages (16, 36, 54) in such a way that the flow rate through the passages covered by the closing structure is lower than the flow rate through the uncovered passages (16, 36, 54). The invention is characterized in that guide means (22, 44) are arranged outside a passage area of the housing-mounted throttling structure (14, 34, 54) defined by passages (16, 36, 52), said guide means (22, 44) acting to support and guide the movable closing structure (18, 40, 56) spaced from the housing-mounted throttling structure (14, 34, 52). |
