The solenoid valve is an industrial equipment controlled by solenoid, which is used to adjust the direction, flow, speed and other parameters of the medium in the industrial control system. There are many types of solenoid valves, and different solenoid valves play a role in different positions of the control system.

Details
The so-called pneumatic system is a control system that uses gas as the medium. In pneumatic systems, the medium for this energy source is usually air. When in actual use, the volume of air in the atmosphere is usually compressed to increase its pressure. Compressed air mainly performs work by acting on pistons or blades. In pneumatic systems, the function of electromagnetic valves is to adjust the various states of compressed air according to the control requirements in the control system. The pneumatic system also requires the cooperation of other components, including power components, actuator components, switches, display equipment, and other auxiliary equipment. The power components include various compressors, and the execution components include various cylinders. These are all indispensable parts of the pneumatic system. The valve body is an important device for achieving control algorithms.
For example, a one-way valve allows compressed air to enter the air tank from the compressor, and when the compressor is closed, it prevents the compressed air from flowing in the opposite direction; The safety valve can discharge compressed air when the pressure inside the air storage tank exceeds the allowable limit; The directional control valve controls the direction of movement by alternately pressurizing and exhausting the two interfaces of the cylinder; The speed regulating valve can easily achieve stepless speed regulation of the actuator.
