Abstract
A dual coil solenoid valve is disclosed for a fuel gas control valve, which comprises a stationary coil assembly and a moving coil assembly, wherein both the stationary coil assembly and the moving coil assembly consist of a magnetic core and a coil. Grooves are provided on the inside of the magnetic cores and coils are arranged in the grooves of the magnetic cores. The stationary coil assembly and the moving coil assembly have an equal cross-sectional area and are arranged oppositely with their axes coinciding with each other. The coils are arranged in the grooves of the magnet cores in such a way that the leakage flux can be reduced and the electromagnetic forces can be increased.
