Cleaning how to ct valves

Hey anyone now of a cleaning how to for chassis tech valves. Cleaned them up but front left is still sticking. I know there shit but don't have the dollars to upgrade atm.

Cheers for any help

which of there valves do you have?

If this is the valve you have...

Then all you have to do is unscrew the top...they are real easy to take apart...then clean them with a cleaning agent...i use a cannon plug cleaner...then lub it, and my worked fine.....

However i know they have been know to issue these with faulty uh...valve internals...i had the same prob and i called AIMIND and they sent me rebuild kits to me...if you ahve to pay for them they are only 1 a peice...

Yeh they are the ones. Ive took them all apart and cleaned and lubed them up but yeh, one is still sticking and cant figure out why.

when you take them apart, there are two pieces...looks like a bullet, well the bottom part has a littel rubber graumet lookin piece. Well they are known to fall out...it might be in the beginings of pulling out....or it did pull out....if you dont have that groumet, then it may be in the valve block somewhere...or i guess if you got the switches from aim, they may be stickin also....

Everything seems to be in place properly and have cleaned them several times but still not workin. It pumps up, but really slow and dumps really slow just the same. Could it be anything else?
