The utility model discloses a moving coil type gas proportional valve, including a gas channel in the gas channel wall, the relative position of the gas input and output an opening, a gas input opening and the output opening staggered, the gas channel openings corresponding in the output and the position of the gas regulating and stabilizing device. An electromagnetic valve arranged at the output opening and the regulating and stabilizing device are composed of a two way stop valve mechanism, and the reliability of the cut-off is increased by 50%, and the sealing capability is improved. The cut-off and voltage regulating mechanisms operate separately so that each component takes on its respective role and does not interfere with each other. The utility model adopts external permanent magnet to form a permanent magnetic field by an electromagnetic coil in the middle, due to current changes in the regulation of the force on the coil coil and the periphery between the permanent magnets to change to change the coil lift, because the coil as a soft material does not exist in the hysteresis phenomenon, so the quick action, reaction speed more than 50%.
