Festo solenoid valve

FESTO solenoid valve automation infrastructure components used to control the flow direction, belonging to the actuator; normally used for machine control and industrial valves above, control the direction of the medium, so as to achieve control of the valve switch.
Working principle of the solenoid valve closed chamber with holes in differentlocations, each hole leads to a different pipeline, cavity intermediate valve, on both sides of the two electromagnets, which surface of the magnet coil is energized the valve body will be are attracted to which side, through the control valve body moves to block or leak oil discharge hole, and into the hole is always open, the hydraulic oil into the drain line, and then to push the oil through the oil pressure cylinder piston, piston driven piston rod, piston rod driven by a mechanical device to move. So that the electrical current through the control of the electromagnet off on the control of mechanical motion.
