rebuildin vavles

dose any one no how to rebuild this vavles that where giving to me

damn i have no clue about that style...

damn thats old school

well all i remember is there are a bunch of seals inside. not sure what set of allen head bolts you remove.

yea i all ready no there a bunch of o riing in it i have tackin it a part and put it back

they where free so i like to rebuild

those are old aim valves. throw them out. i had a set of those and had 2 of them siezed up on me permanantly and one i was able to free up by disassembling it and soaking it in oil. Those are a spool style valve that were very problematic when water got in them, thats prolly why those ones dont work anymore.

It is also possible that those could still be working and just not plumbed correctly, each individual valve has 5 ports 2 of which get plugged, the way they run through the manifold its confusing because some of the holes in it actually need plugged. even if it does still work i wouldnt put it on anything that you need to be reliable.

they work they just want hold air

wouldnt that mean they dont work?
