御弁。[Claims for Utility Model Registration] 1. A valve hole interposed in the main flow path between an inflow port and an outflow port, a main valve that opens and closes this valve hole, an opening/closing mechanism and a flow rate adjustment mechanism for this main valve. The main valve is opened and closed by the opening/closing operation mechanism, and the flow rate control by the main valve is adjustable by the flow rate adjustment mechanism when the main valve is opened during non-opening/closing operation. A directional control valve featuring: 2. The directional control according to claim 1, further comprising a main flow rate adjustment mechanism for the main valve, wherein flow rate control of the main valve during opening/closing operation can be adjusted by the main flow rate adjustment mechanism. valve. 3. The directional control valve according to claim 1, wherein the flow rate adjustment mechanism is formed by a curvature adjustment screw provided coaxially with the main valve. 4. The directional control valve according to claim 2 or 3, wherein the main flow rate adjustment mechanism is formed by a crest adjustment screw provided coaxially with the main valve.
