A composite flow divider valve in which a pilot hydraulic valve with a relatively large switching flow rate is operated by a solenoid valve, and a position where the input port is divided into both output ports and a position where the flow is communicated with one output port. A pilot hydraulic valve having a 4-port, 2-position solenoid valve, and a relief valve connected to a port of the solenoid valve are combined, and in one position of the solenoid valve, an oil chamber on one end face of the hydraulic valve is connected. A composite flow divider valve that communicates with a tank port, and in the other position, closes only the tank port and allows the other three ports to communicate with each other. 2. The valve according to claim 1, which connects the branch line of the H port of the hydraulic valve to the port of the electromagnetic valve. 3. The valve according to claim 1, in which a small amount of hydraulic oil flows into the H port of the hydraulic valve even in the shutoff position.
