The invention relates to a combined installation electromagnetic jet valve, which comprises a main valve, a pilot valve and an aerial socket, wherein the main valve comprises a jet valve seat block, a main valve cylinder body, a piston seat, a main valve spring, a sealing body, a screw plug, a piston and a sealing ring; the pilot valve is arranged in the jet valve seat block and comprises a pilotvalve spring, a seal cover, a discharge plug, a pilot head, a soft seal, a dynamic magnetic core, a nut, an electromagnet, a main valve cylinder body screw and a seal cover screw; and the piston in the main valve moves in the main valve cylinder body so as to realize opening and closing of a main valve oil port, and the pilot valve arranged in the jet valve seat block controls the position of thedynamic magnetic core in the pilot valve through the charge condition of the electromagnet so as to realize control of the switching of the oil port and further control the motion of the piston in the corresponding main valve. The jet valve realizes switching of the main valve through on and off of the electromagnet of the pilot valve, does not need to compress air, avoids the problem caused by use of compressed air drive, improves the response speed, has high combined installation integration degree, and effectively promotes the installation efficiency.
