The solenoid valve is an industrial device controlled by electromagnetism. It is a basic automatic component used to control fluids and belongs to the category of actuators, not limited to hydraulics and pneumatics.
It is used in industrial control systems to adjust the direction, flow rate, speed, and other parameters of the medium. The solenoid valve can be combined with different circuits to achieve the desired control, ensuring both precision and flexibility.
There are many types of solenoid valves, and different ones play roles in different positions of control systems. The most commonly used are check valves, safety valves, directional control valves, and speed control valves.
