A moment electrified air valve using magnetic coils is provided to prevent airtightness of a valve from being deteriorated due to deterioration of components by switching an air path by using a moment electric signal. A moment electrified air valve(1) using magnetic coils includes a valve body(10), a suction hole(S), left and right discharge holes(C1,C2), left and right exhaust holes(E1,E2), a magnetic coil unit, a cylinder, a check valve, and an anti-shock valve. The suction hole is formed at a lower part of the valve body and sucks air. The left and right discharge holes discharge the air sucked from the suction hole. The left and right exhaust holes are formed at the lower part of the valve body and exhaust residual air in the valve body. The magnetic coil unit is formed at an upper part of the valve body. The cylinder is installed in the valve body, is alternately switched left and right when the magnetic coil unit is momently electrified, and alternately discharges the sucked air into the left and right discharge holes according to the switched directions. The check valve is formed at the lower part of the valve body and opens and closes a first suction path according to air pressure in the valve body. The anti-shock valve is formed at the lower part of the valve body and prevents the air from being suddenly sucked in the valve body.
