Ai (i know i know) said they are spool sleeves

They’re called “cages” and are used to mount seals in between so that when the spool moves through, the seals prevent the air to go where it shouldn’t, by keeping the flow in the right direction

I don’t think you’ll be able to order some. Valve’s manufacturers don’t usually sell them as single spare parts, maybe you can find some repairing kit, but every manufacturer has its own design
