PROBLEM TO BE SOLVED: To provide a direct drive valve which facilitates regulation work, increases the degree of freedom of design, and reduces size and weight. SOLUTION: A direct drive valve comprises control valves 33a and 33b to independently control a plurality of hydraulic systems of the displacement of spools 30a and 30b contained in sleeves 34a and 34b in an axial direction, and motors 21a and 21b to drive the spools 30a and 30b of the control valves 33a and 33b. Further, the control valves 33a and 33b are arranged in parallel to each other, and link mechanism 24a, 24b, and 25 to interlock rotations of motors 21a and 21b are provided. |
