[0002] Solenoid valves are industrial equipment controlled by electromagnetics. They are basic automation components used to control fluids. They are actuators and are not limited to hydraulic or pneumatic. They are used in industrial control systems to adjust the direction, flow, speed and other parameters of the medium. Solenoid valves can be used with different circuits to achieve the desired control, and the accuracy and flexibility of control can be guaranteed. There are many types of solenoid valves, and different solenoid valves play a role in different positions of the control system. The most commonly used ones are check valves, safety valves, directional control valves, speed regulating valves, etc.
