The high-temperature double-position magnetic self-locking electromagnetic valve comprises a valve body and a pilot valve, a coil 1 and a coil 2 are arranged on the two opposite sides of the pilot valve, the valve body is a three-way valve body, and a balance motion rod is arranged in the valve body; the pilot valve is connected to the valve body through an adapter disc, a piston cavity is formed among the pilot valve, the adapter disc and an outlet channel B of the valve body, a piston arranged in a floating mode is arranged in the piston cavity, an induction magnetic ring is arranged on the side face of the piston, and a passive magnetic switch corresponding to the induction magnetic ring is arranged on the outer side of the valve body. The two passive magnetic switches are arranged in the vertical direction of the outer side of the valve body. And the coil does not need to be electrified for a long time, so that the reliability and the service life are higher. 本发明公开了一种高温双位磁性自锁电磁阀，包括阀体和先导阀，所述先导阀的两对侧设置有线圈1和线
