There are many types of solenoid valves, according to the number of ports
Three-way solenoid valve Series Series Series Series Solenoid Valve Three-way valve has an inlet (denoted by or), an outlet (denoted by or) and an exhaust port (denoted by or). Three-way solenoid valves are also available with one inlet and two outlets, as distribution valves or with two inlets (and indicated) and one outlet, as selector valves.
Five-way solenoid valve series series series series series series series series series solenoid valve The five-way solenoid valve has one inlet, two outlets and two exhaust ports. The passage is, (that is, air intake through the port, exhaust through the port) or,. The five-way solenoid valve is generally used to control the reciprocating direction of the double-acting cylinder.

Two-way solenoid valve series series series series series series series solenoid valve. The two-way solenoid valve has an inlet and an outlet to control the on and off of gas.
Normally open type and normally closed type of solenoid valve
Normally open type and normally closed type are divided into open and closed solenoid valves. When there is no control signal, the same is a normally-on type (generally expressed by ""), and when it is disconnected, it is a normally-off type (generally expressed by ""). If the flow direction in the channel is not limited, it is called an on-off valve. Normally-on and normally-off solenoid valves are not allowed to flow in the reverse direction, because reverse pressure will cause the one-way sealing ring to become unsealed or fail to seal.
Operating voltage of solenoid valve
The power supply voltage that can be used by solenoid valve is also relatively wide, the common ones are DC, AC, etc. In addition, the operating voltage of solenoid valve can also be customized. The AC solenoid valve has a buzzing sound, a large stroke, and a large suction power. There is no buzzing sound in the DC solenoid valve. When the stroke is large, the suction force is very small, that is, the starting force is small. The pneumatic current of the AC solenoid valve is large, sometimes more than twice the holding current. If the moving iron core is stuck, the starting current continues to flow, and the coil will become very hot and may even be burned. The AC solenoid valve should not be switched on and off frequently. The service life is not as long as that of DC solenoid valve. The current of the DC solenoid valve depends on the coil resistance and has nothing to do with the stroke size. Therefore, the coil will not be burned when the moving iron core is stuck. The DC electromagnet can be switched on and off frequently, making the operation safe and reliable. However, when the voltage is staggered and the current flowing through is too large, the coil will still be burned.
The action mode of solenoid valve
According to the action mode, solenoid valve can be divided into direct-acting type and pilot type. What is a direct-acting solenoid valve? Direct-acting solenoid valves directly rely on electromagnetic force to reverse the direction of the valve core. The direct-acting solenoid valve has a small diameter and is often used for small flow control or as an electromagnetic pilot valve for pilot-operated solenoid valves. The pilot solenoid valve consists of a pilot valve and a main valve. Relying on the air pressure output by the pilot valve, the main valve core is pushed to change direction by controlling the piston and so on. Most solenoid valves with large diameters are pilot-operated solenoid valves. Pilot solenoid valves are divided into internal pilot solenoid valves and external pilot solenoid valves.
Wiring methods of solenoid valves
There are various wiring methods for solenoid valves, including direct outlet methods, such as wire outlet type with terminal block, conduit terminal block type, tangible socket type, tangible socket type, etc. There are also several wiring methods and so on.
When the electromagnetic coil of the solenoid valve is energized, the static iron core generates electromagnetic attraction to the moving iron core, and the electromagnetic force is used to switch the valve core to change the direction of gas flow, thereby achieving on-off reversal, etc. Solenoid valves are easy to realize electrical joint control and complex control, and can achieve long-distance operation. Therefore, solenoid valves are currently used more and more widely.
