ELECTRICALLY OPERATED VALVE SYSTEM

An electrically operated valve system includes: a first switching element and a second switching element connected in series to an electric power supply; a third switching element and a fourth switching element connected in series to the electric power supply; diodes; a coil connected between a first middle point and a second middle point, the coil being wired such that a valve opens when the second switching element and the third switching element are opened and the first switching element and the fourth switching element are closed; a shutoff switch configured to shut off a path between a positive electrode of the first switching element and the electric power supply; and a capacitor connected at one end of the capacitor between the shutoff switch and the first switching element and connected at the other end of the capacitor to the negative electrode of the electric power supply.
