Could you please help explain the meaning of each symbol on this gauge in the diagram?

XV is the type of valve; XSV is a solenoid valve. I134 is the interlock code, XSC134 is the signal indicating that the valve has closed fully, and XSO134 is the signal indicating that the valve has opened fully
What is the difference between this gauge and the one above?
As can be seen from the diagram, there is an additional element named XZT; this is likely a valve position feedback signal, of analog type

What is the significance of representation? Also, why are there two solenoid valves?
I’ve never seen this kind of design diagram before; I’m learning about it
In the diagrams above, solenoids A and B are used in parallel, which constitutes a high-availability configuration: as long as one of solenoids A or B is energized, the valve opens; if neither of them is energized, the valve closes
