So far, the modes of action can be divided into three types: direct action, recoil and pilot.

From the industrial solenoid valve disc structure and material can be divided into diaphragm recoil solenoid valve and piston recoil solenoid valve; Pneumatic high frequency solenoid valve pilot can be divided into: diaphragm pilot and pilot piston solenoid valve; Soft seal type soft seal solenoid valve; Working principle of direct moving solenoid valve: normally closed solenoid valve is energized, the electromagnetic coil produces electromagnetic attraction, the spool will be lifted, the closed parts leave the seat, the valve seal, when the power is off, the electromagnetic force disappears, the closing element is pressed by the force of the spring, close the valve.

Features: vacuum, negative pressure, zero differential pressure can work normally. The size of the magnetic head below DN50 is large. Recoil solenoid valve working principle: its principle is the combination of direct action and guidance. Solenoid valve start, first open the auxiliary valve, when the main valve chamber pressure is greater than the upper chamber pressure, through the differential pressure and solenoid valve at the same time to open the valve; If the solenoid valve is powered off, the auxiliary valve uses spring force or medium pressure to push the closure piece so that the valve closes downward.
