Abstract
A solenoid valve controlled by wireless communication, in which the operation of the valve is controlled by wireless communication, thereby reducing costs and labors necessary for installation and maintenance. The solenoid valve includes a valve body having an inlet port, through which fluid is introduced, and an outlet port, through which fluid is discharged; a plunger movably mounted inside the valve body to open or close one or both of the inlet and outlet ports; a solenoid, which drives the plunger to a position, in which the plunger opens or closes one or both of the inlet and outlet ports, when electric power is supplied; and a communication module provided on the valve body. The communication module receives a wireless control signal transmitted from outside and controls the electric power supplied to the solenoid valve depending on the wireless control signal.
