Definition of solenoid valve

Solenoid valve is electromagnetic controlled industrial equipment, used in industrial control system to adjust the direction, flow, speed and other parameters of the medium. There are many kinds of solenoid valves. Different solenoid valves play a role in different positions of the control system. The most commonly used are one-way valve, safety valve, direction control valve, speed regulating valve and so on. Solenoid valve is controlled by electromagnetic effect, and the main control mode is controlled by relay. In this way, the solenoid valve can match different circuits to achieve the desired control, and the accuracy and flexibility of the control can be guaranteed.
Solenoid valve
The rod-shaped object is electrically controlled stem, which can open or close the valve stem by electromagnetic force.
The following is an example of pneumatic system to illustrate the application of solenoid valve in industrial control. The so-called pneumatic system is a control system based on gas. In a pneumatic system, the medium of energy is usually air.  When used in real time, the volume of air in the atmosphere is usually compressed so as to increase its pressure. Compressed air works mainly by acting on the piston or blade.
In the pneumatic system, the function of the solenoid valve is to adjust the various states of the compressed air in the control system. The pneumatic system also needs the coordination of other components, including the power components, the actuator, the switch, the display equipment and other auxiliary equipment. The power element includes various compressors, and the execution elements include various cylinders. These are indispensable parts of the pneumatic system. The valve body is an important device to realize the control algorithm.
For example, a one-way valve allows compressed air to enter the gas tank from the compressor, and when the compressor is closed, the compressed air is prevented from flowing in the opposite direction; the relief valve can discharge the compressed air when the pressure in the gas tank exceeds the allowable limit; the direction control valve controls the direction of motion by alternately pressing and exhausting the two interfaces of the cylinder. The degree control valve can realize the stepless speed regulation of the executive element simply.

The solenoid valve can not only be used in the pneumatic system, but also can be used in the oil pressure system and water pressure system, such as low power and non oil supply small electromagnetic reversing valve, sealing parts do not need oil supply, the exhaust gas will not pollute the environment, can be used in food, medicine, electronics and other industries.

Electromagnetic reversing valve
Now, solenoid valve technology and control technology, computer technology, electronic technology, has been able to carry out a variety of complex control. For example, you can apply the solenoid valve to the intelligence
