PROBLEM TO BE SOLVED: To provide a hydraulic system capable of giving priority to an actuator of the highest priority when dividing flow by using a load pressure sensing priority valve for dividing flow into a plurality of actuators comprising the actuator of the highest priority. SOLUTION: Output pressure inside a pipeline 32 works to the priority valve 3 as the pressure for operating the priority valve 3. Load detecting pressure of the actuator of the highest priority is taken by a pilot pipeline 36 through a solenoid operated selector control valve 5, and joined with one of the output pressure. The priority valve 3 can be maintained at a first position 3-1 by energizing force of a spring 4 by closing the solenoid operated selector control valve 5. The priority valve 3 can be made to function as an acceptable priority valve to be switched in response to the output pressure by opening the solenoid operated selector control valve 5.
