Pilot solenoid valve


When the pilot solenoid valve is energized, the solenoid generates electromagnetic force to open the pilot hole, which makes the pressure of the upper chamber drop sharply, forming a high pressure difference at the closing part, and then the closing part is pushed up by the pressure, and the valve When the power is turned off, the electromagnetic force disappears, the pilot hole is closed under the action of the spring, and a pressure difference between the upper and lower parts is formed at the closing part, and the closing part is pushed down and the valve is closed.
