摘要： It is addressed to provide a hydraulic control valve for preventing high-speed rotation of a valve body of a check valve incorporated in the hydraulic control valve of a type that pressure oil is supplied from a tandem path and a parallel path via the check valve. A check valve unit (CH) is constituted by a main unit (6) and a valve body (4a) of a first check valve (4). A throttle (3) is provided on a right side of an O-ring groove (6a). On a main unit side, there is formed a cylindrical housing portion (6h) in which a threaded portion (d) is formed on an outer peripheral portion for fixation to a casing of the hydraulic control valve. On an inner peripheral surface of the housing portion, a groove (8) is formed in an axial direction. Meanwhile, the valve body of the first check valve (4) has a rib (7). At a time of assembly, the rib (7) is inserted into the groove (8) of the main unit as indicated by an arrow. After the valve body is assembled to the main unit and fixed to the casing, even with imbalance such as phase shift of the pressure-oil path (4b), the rib having fit into the groove, namely the valve body, is prevented to rotate while it is slidable in the axial direction. Thus, the casing of a seating part of the valve body is not abraded.
