[Problem] To provide a dual 4-port electromagnetic valve in which the function of two 4-port valves has been conferred on a single electromagnetic valve, the valve being small and having an efficient design structure. [Solution] A dual 4-port electromagnetic valve comprising: two spools (8a, 8b) that independently slide inside a valve hole (7); two pilot valves (4a, 4b) for individually driving the two spools; a main supply port (P) that is in communication with the valve hole (7) at a position in which the two spools face each other; first and second output ports (A1, A2) that are in communication with the valve hole on both sides of said main supply port (P); first and second discharge ports (E1, E2) that are in communication with the valve hole on both outer sides of said output ports (A1, A2); third and fourth output ports (B1, B2) that are in communication with the valve hole on both outer sides of the discharge ports (E1,E2); and first and second supply ports (P1, P2) that are in communication with the valve hole on both outer sides of the output ports (B1, B2). The main supply port (P) and the first and second supply ports (P1, P2) are in communication with each other. |
