1638255091 VALVE SOLENOID For HITACHI JR180-3

IThe working principle of solenoid valve is based on the principle of electromagnet. It consists of a coil, an iron core and a valve body. When the current passes through the coil, the coil generates a magnetic field, which attracts the iron core to move upward, opens the valve and allows the fluid to pass through. When the current is cut off, the magnetic field disappears, and the iron core returns to its original position under the action of gravity or spring, closing the valve and preventing the fluid from passing through.

Solenoid valve is a device that uses electromagnetic effect to control the on-off of fluid. When the solenoid is energized, the coil inside it will generate a magnetic field to attract the iron core to move, thus changing the position of the valve core and controlling the flow path of the fluid. When the solenoid is de-energized, the magnetic field disappears, the valve core is reset under the action of the spring, and the fluid flow path changes accordingly.
