The use of stainless steel piston greatly enhances the bearing capacity of the valve, making the piston ring free expansion, metal piston and valve chamber without direct friction, to overcome the phenomenon of easy jam. The corresponding medium fracture is sealed with material, which improves the sealing performance of the valve and prolongs the service life of the solenoid valve.

It is mainly composed of new solenoid valve solenoid coil, valve body, valve cover, main valve body, moving iron core, moving iron core spring, moving iron core pressure spring, pressure relief hole, etc.

Working principle of conductive solenoid valve:

The micro solenoid valve is normally closed. When the electromagnetic coil is energized, the active iron core is inhaled, opening the discharge hole, reducing the pressure on the main spool, using the pressure difference to push the main spool upward. After opening the electromagnetic coil, the movable iron core falls due to its own weight and the action of the movable iron core spring, closing the vent hole, forming pressure on the upper surface of the main spool.

For normally open solenoid valve, solenoid valve coil is energized, exhaust port and normally open solenoid valve form closed state.

Principle of signal lamp feedback device:

Open the solenoid valve, connect the public line with the switch signal line, and close the signal line.

When the solenoid valve is closed, the public line is connected with the closed signal line, and the signal line cannot be connected.
