how rebuild air valves

do you just unscrew the main nut on the shaft,then unscrew the four screws and pull out all the gaskets and clean it up and reasimble it back together or is there something else involved????

thanks

i know i cant spell sorry.....

i think under the tech library on here they show u how to rebuild valves

That's about it. But once you get them apart you will realize that you need new diaphragms, But the company you bought your valves from no longer exists, and your screwed.

Actually, that's just my experience, I hope the same doesn't happen to you.

thanks guys
