<p>PROBLEM TO BE SOLVED: To provide an electromagnetic valve device which stabilizes a valve-opening maintaining state and a valve-closing maintaining state of a valve, and suppresses power consumption at the switching of the valve.SOLUTION: When moving and driving a plunger 1 to one direction, either of a positive first prescribed voltage or a negative first prescribed voltage is applied to a coil 4, a valve main body is opened and closed by operating a ball valve 10 via the plunger 1 accompanied by the movement of the plunger 1 to a center axial direction, a separation force for separating the plunger 1 from a magnet adsorption state by a spring 14 is large with respect to a magnet suction force by which a magnet unit body adsorbs the plunger 1 in a state that the plunger 1 approximates the magnet 17, and in the state that the plunger 1 approximates the magnet 17, a control unit applies a small first micro voltage to the coil at an absolute value by a first prescribed voltage, and stabilizes a valve opening state while saving power.</p> |
