Festo solenoid valve

ESTO 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
