What the hell is this? Pneomagnetic valve

What the hell is this, air driving air? ?
Pneumatic control valve. The pressure of compressed air is used to control the opening and closing of the air circuit
A pressure-controlled directional valve uses gas pressure to move the main spool, thereby changing the direction of the gas flow. Based on the control method, it is divided into three types: pressure control, pressure relief control, and differential pressure control. Pressure control refers to the fact that the pressure of the control signal applied gradually increases; when this pressure reaches the operating pressure of the valve spool, the main valve changes direction ； Pressure relief control refers to the reduction of the pressure of the pneumatic control signal; when it drops to a certain pressure level, the main valve changes direction ； Differential pressure control causes the main spool to change direction under the action of the pressure difference between the two ends.
Please provide a detailed explanation for this case, thank you!
This isn’t an electromagnetic valve, right? If it’s a pneomagnetic one, there has to be an electromagnetic valve outside as well
Solenoid valve? Where is the electricity? ? Where is the magnet? ? Obviously, this is a pneumatic switch valve. The air path switching is driven by air pressure.
Such pneumatic control valves are generally used in small screw air compressors to control the opening and closing of the intake valve, thereby controlling the loading and unloading of the air compressor!
