Pneumatic solenoids

Our team is currently trying to figure out why our solenoid valves(M4V210-06-12VDCFL) arent working. They sound like they are firing but nothings moving, i cannot find any info on these if anyone has experience with them then any help would be appreciated.

Could you take a picture of what the system looks like? What the expected behavior is?

Here some photos of the part itself

We are kinda trying to figure out what it excatly does…

It won’t move without a minimum amount of air pressure (probably 5-10psi). Apply pressure to the P port and it should come out of the A port, switching to the B port when power is applied.
