The present invention provides a control valve capable of suppressing inflow of foreign substances included in a fluid into a sliding part. The control valve according to an embodiment of the present invention comprises: a body where a valve hole (18) and a guide hole (26) are formed to be linked along an axial direction through a middle pressure room (24), a port (14) to introduce the fluid into the middle pressure room (24) is formed to be opened toward a side, and a port (12) to make the fluid which has passed through a valve hole (18) discharged; a valve body (33) which opens and closes a valve part by coming in contact with a valve hole (18) from the port (12); and an operating rod (50) which is supported to be able to slide in the guide hole (26), and is prepared integrally with the valve body (33) by penetrating the valve hole (18). A stepped part (27) is formed in the same axis as the guide hole (26) between the guide hole (26) and the port (14) in the middle pressure room (24), and comprises a bottom surface to catch the foreign substances flowing in through the port (14), wherein the diameter of an inner wall (31) demarcating the stepped part (27) is greater than the diameter of the valve hole (18). |
