I have another question regarding basic instrumentation knowledge

As shown in the diagram, I would like to ask about its functions; it would be great if you could provide detailed information on the process from intake to exhaust. Thank you
Two-position five-way. Solenoid valve – search on the forum.
Two five-way valves: in the off state they are at the bottom, and in the on state they are at the top
Based on the location of your photos: the two boxes at the top and bottom in the image are not two chambers; rather, they represent the states when power is applied and when it is not. The upper box indicates the direction of fluid flow and the ports when power is applied, while the lower box shows the direction of fluid flow and the ports when no power is present. This two-state drawing method shows the pipeline connections in a de-energized state, that is, within the box below. The boxes indicate the operating positions of the solenoid valves; 2 boxes mean there are 2 positions. The arrow inside the box indicates that the fluid is in a connected state, but the direction of the arrow does not necessarily represent the actual direction of the fluid flow. The T-shaped symbol inside the box indicates that the path is blocked. The number of interfaces connected outside the box indicates the number of \"ways,\" and this valve is a 2/5 way valve.
Floor 7 explained it in great detail: 1 is the air intake, 2 and 4 are connected to the two cylinders respectively; 3 and 5 correspond to the exhaust ports on both sides. When the solenoid valve is powered, 4 allows air to pass through, while 2 does not allow air to pass through, and at the same time the cylinders are connected to 3 for exhaust. The valve moves in one direction. When the solenoid valve is not powered, the situation is exactly the opposite
Below is the natural state and when there is no power supply; above is how the air path is connected when power is applied
It should be two five-way pilot-operated solenoid valves; when not powered, 1-2； 4-5
Two-position five-way valve: 1 for intake, 2 and 4 for outlet connected to cylinders (the coil controls the expansion and contraction of the cylinders), 3 and 5 for exhaust, can be connected to a silencer
