The invention provides a compact rapid two-position three-way electromagnetic directional valve provided with an internal channel. The compact rapid two-position three-way electromagnetic directional valve provided with the internal channel comprises a shell, a movable iron core, a static iron core and an end cap. The movable iron core is in clearance fit with a second inner hole of the shell, a drainage groove is formed in the columnar surface of the movable iron core, wire strainer structures are arranged on the two end faces of the movable iron core and used for balancing the pressure difference between the two sides of the movable iron core so as to reduce the load of the static iron core, and cylindrical bosses are arranged on the central portions of the two end faces of the movable iron core and used for blocking a fluid channel of the movable iron core; the static iron core comprises a coil support and a coil and is in clearance fit with a fifth inner hole of the shell in the radial direction, and the static iron core is sealed through a first O-shaped sealing ring and positioned in the axial direction through the end face of a first inner hole of the shell; the section of the coil support is approximately in an I shape, a step hole is formed in the center of the coil support, and the coil is wound on the periphery of the coil support; a coil wire is guided out from a sixth inner hole in the shell; the inverted-L-shaped channel is formed in the end cap and used for guiding out liquid from the static iron core into a seventh inner hole of the shell to be drained; and the end cap is in clearance fit with a fifth inner hole of the shell and sealed through a second O-shaped sealing ring, and the end cap is fixedly connected with the shell.
