量フローコントロール装置。 A logic type pressure reducing valve is provided on the upstream side of a hydraulic circuit through which a large flow of fluid flows, and a logic type throttle valve is provided on the downstream side. The pressure difference between the pressure on the upstream side of the pressure reducing valve and the pressure on the downstream side of the throttle valve is created by the pilot pressure introduced through the throttle between the flow control valve and the pressure control valve provided in the pilot circuit connecting the hydraulic circuit. The pressure control valve of the pilot circuit is controlled by electromagnetic proportional pressure control. A large flow rate flow control device using a logic type valve, characterized in that the logic type throttle valve is configured with an electromagnetic proportional logic type throttle valve.
