English 
The valve operates by rotating a central spool or disc inside the valve body to direct the airflow to different ports. By adjusting the position of the spool, the valve can control the direction of air flow, allowing it to switch between different output ports or block airflow altogether.
Four-way air control valves are commonly used in industrial applications such as automation, machinery, and equipment control. They are essential for controlling the movement of pneumatic actuators, such as cylinders or rotary actuators, by directing the compressed air to the desired ports to either extend, retract, or stop the actuator's movement.
