How does this solenoid valve work?

How do I understand this air circuit diagram? Thank you
The ASCO531 series of cartridge valves are two-position five-way valves: 1 is for intake air, 3 and 5 are for exhaust air, while 2 and 4 are connected to PU pipes for controlling the flow of air and enabling direction changes. Once the connection pipes are attached to the equipment, you can manually control the opening and closing as well as the direction change of the valve; there’s an operation mechanism at the bottom, and after using it a few times you’ll understand how it works. So, what kind of device is this? There are wheels below as well; do they control the linear cylinder?
The working principle of the solenoid valve: in the initial state, 1 and 2 are for air intake; 4 and 5 are for air exhaust. When the coil is powered, an electromagnetic force is generated by the stationary core, causing the pilot valve to operate – 1 and 4 become for air intake, while 2 and 3 are for air exhaust. When power is cut off, the pilot valve returns to its original position under the action of the spring.
In the diagram, 1 represents intake, while 3 and 5 represent exhaust. By activating or deactivating the solenoid valve, the 24 air paths are switched, thereby enabling the cylinder to move.
In the diagram, 1 represents intake, 3 and 5 represent exhaust, while 2 and 4 represent venting; this type of solenoid valve also has manual control.
When the coil is powered: 14 is active, 23 is active, 5 is inactive. When the coil is de-energized: 12 is active, 45 is active, 3 is inactive
