XCMG 200 pilot safety lock rotary solenoid valve is generally a pilot solenoid valve

   Structural basis: mainly composed of electromagnet, valve body, pilot hole, valve core, spring and other parts. When the electromagnetic coil is not energized, the valve core is in the closed position under the action of the spring force, blocking the pilot hole.

     When the electromagnetic coil is energized, a magnetic field is generated, and the electromagnetic force overcomes the spring force to attract the valve core, breaking the seal between the valve core and the valve seat, and the pilot hole opens. At this time, the upper chamber of the solenoid valve is depressurized through the pilot hole, and the pressure in the upper chamber drops rapidly, forming a pressure difference around the main valve core, with the upper part lower and the lower part higher. Under the action of the pressure difference, the fluid pressure pushes the main valve core upward, the main valve port opens, and the pilot oil can flow through the solenoid valve to the control oil circuit of the handle, foot valve and solenoid valve group.
