PROBLEM TO BE SOLVED: To provide a hydraulic valve coping with a high flow rate of pressure oil. SOLUTION: A port 17 to suck pressure oil to the inner periphery of a main spool 12 is opened, and the position of a pilot spool 15 fitted in the inner periphery of the main spool 12 is switched. By guiding pressure oil to cylinders 18 and 19 selectively formed on both sides of the main spool 12, the main spool 12 is moved to the opposite side to the cylinders 18 and 19 to which pressure oil is guided, the position of the main spool 12 is switched, and an opening amount of an outlet port 14 is controlled.
