PURPOSE: An electronic valve for controlling LPG fuel is provided to simply and precisely control the fuel amount of an LPG engine to maintain a proper air-fuel ratio and reduce the harmful exhaust gas. CONSTITUTION: An electronic valve for controlling LPG fuel includes a control valve(1) of which valid sectional area passing though fuel is deformed linearly according to a control signal, and a solenoid having one or two independent coils(4,5) for deforming the valid sectional area of the valve linearly, wherein an armature(3) in the solenoid connected to the control valve is linearly deformed by the dynamic characteristics of the force applied to the armature by PWM(Pulse Width Modulation) above a predetermined frequency, inertia and the force applied to a spring(6).
