PROBLEM TO BE SOLVED: To provide a dual four-port solenoid valve having a small and rational design structure, with one solenoid valve having a function of two four-port valves.SOLUTION: A dual four-port solenoid valve includes: two spools 8a, 8b independently sliding inside a valve hole; two pilot valves 4a, 4b individually driving the two spools; a main supply port P communicating with the valve hole at a position where the two spools are opposite to each other; first and second output ports A1, A2 communicating with the valve hole on both sides of the main supply port P; first and second exhaust ports E1, E2 communicating with the valve hole on both outsides of the output ports A1, A2; third and fourth output ports B1, B2 communicating with the valve hole on both outsides of the exhaust ports E1, E2; and first and second supply ports P1, P2 communicating with the valve hole on both outsides of the output ports B1, B2. The main supply port P and the first and second supply ports P1, P2 communicate with each other.SELECTED DRAWING: Figure 1 |
