Excuse me, could you take a look at the air circuit of this pneumatic valve? Thank you

In this pneumatic valve circuit, what is the function of these 5 pneumatically controlled valves?
As can be seen from the diagram, the air-controlled valve 5 is the main switch for controlling the air circuit of the solenoid valve: when there is air supply (no fault in the air source), the control of the solenoid valve takes effect; when there is no air supply (a fault in the air source), the control of the solenoid valve does not function.
What was said upstairs is correct; the air control valve 5 serves as the main switch for controlling the air circuit via solenoids. When the air supply pressure is too low or there is a fault, the dual-solenoid control system for the air circuit will not function. And this valve should be used in relatively important interlocks; two solenoids are connected in parallel, and the valve will move to the fault position and open only when both solenoids lose power or fail at the same time
By the way, which department at Hengli does your brother work in?
Of course I know the instrumentation department, which workshop handles the instruments: lol
Is there so much constant force? Heheda
