How to take apart cvx Valve?

[Andredy]

I had to buy a new valve because my last one busted but I want to know how you take it apart so i can take my old one apart and see what parts are still any good. (I just need to know how to get the outer plastic shell off cause mine was welded on there with that strong red locktite)

Take it completely out of the marker. Disconnect your hose, LP Chamber, whatever's attached to it. Then, use a pencil to pop the valve out. Simple as that.

Close! But that only takes the valve out the powertube.

To disassemble the valve itself, you need a 90* pick, a pen, and a pencap.

You push down the brass fitting on the front end of the valve so that it goes down below the input hose (the 1/8" hose on the bottom). With it down past that, you put the pencap in there. Then take out the pen. The cap holds brass fitting down. So now you can work on the valve snap ring.

The 90* pick now comes in use. You work with the snap ring, starting with the bottom. You try to get inbetween it, since it's like a key-ring where it overlaps itself. When you finally get in there, you spiral the pick around clockwise to spiral the ring out of the valve.

Now you can remove the pen cap. All the valve internals can now come out, and you can look them over. There should be brass end plug, spring, and valve stem.

Chances are, you just got to replace the O-ring on the brass fitting, if you had a leak. Then to re-assemble it, basically do what I said in reverse. Using the pen and pen cap trick, and ****ing around with that snap ring for a good half hour for it to do what you want.

Ah, you're correct, I misread his post. I thought he just wanted to know how to get the valve outta the powertube.

Great post Meph! :)

Send it into Tippmann: they'll do it for you and they'll guarentee their work. And, you'll have it back in a week.

Meph you forgot to mention that after you remove the cup seal/valve stem and spring that there is a brass disc that needs to be removed and another o-ring. The brass disc and oring are what seals the cup seal and I have found that the oring under the disc is responsible for most of the valve leaks I've fixed. Take note of how the disc is installed and be sure to replace it in the same position as there are two sides to the disc. It has two rased circles of different heights on it and the shorter one needs to engage the oring and the taller one the cup seal.

procarbine.com m98 cvx valves are very similar even tells you how to mod it for lp use

Here is a pic of the internal parts. There should also be an o-ring on the right but I didn't have one handy...I think it's that same size as the one on the plug on the left.

With the o-ring...

Blah, of course I had to forget that. That's what I get for rushing through the description of the bloody valve.
