I just got shot in the mouth by my on/off valve

[xen_100]

I dont get it, how is that a solution? you cant just pull that QD off to degas, you will destroy the QD over time.

besides, it is not a line degas problem. the problem is that the valve holds in some amount of air after you degas.

agd, it Always shot out in a classic valve.. but never in a retro for me

I've been doing it for about 3 years and it hasn't hurt anything yet, except my ears from the loud hiss it makes haha.

Over the course of 15 or so years, I have NEVER had an on/off assemply shoot out on me. Retro, classic...take your pick. I have serviced thousands of AGD valves, and my conclusion has come to the fact that some people are just not de-gassing properly. Get the right parts to degas the marker properly. And as to the post on using pliers on macro fittings to de-gas, that is the lamest way I have ever heard. It is also VERY unsafe. Dont do it!

I think it's great that there is some interest in finding a solution to this...

however, some still don't quite understand what we are talking about...

1. The tank on/off is unscrewed

2. The quick disconnect is disconnected

3. The trigger is pulled

4. All air is totally out of the ASA, air hose, etc.

The air is out of everywhere except the valve...something is holding the pressure in the valve. I've tried just about everything, pulling the trigger, moving the bolt around, etc. Nothing gets out the air pressure except slowly backing out the valve, in which the on/off is scraping against the inside of the body/rail due to the force of the air pushing it outwards. This is actually the reason why I haven't bought a ULE body...the face of the on/off assembly (brass) is scratched and gouged due to this problem...since the body is s/s, nothing happens to it. I wouldn't doubt the inside of a ULE would get all torn up from backing out the valve with an on/off scraping against it.

Remember-if you took the tank off the gun, the air hoses off the gun, everything off, except leave the valve in the gun, that is where the pressure is built up. Just wanted to make sure ya'll got the picture

My problem has been in an Emag valve...the ONLY valve I have with LX.

AGD- As I stated it was with a CLASSIC valve!

It happens very sporadicly and IT HAS NOTHING TO DO WITH RELEASING THE AIR IN THE AIR LINES! WE ARE DOING THIS PROPERLY!

omg...

i dunno bout any one else but that title is the funniest thing i have ever read...i seriously spit out my pop and pizza all over my monitor and key board...i couldnt stop laughing, OH and sorry bout the problem, cant say it has ever happened to me. i also unscrew my tank and shoot it down at the same time...

Thanks Tom!!!

Are you sure you guys aren't using quick disconnect fittings with check valves in them that are used for fill nipples on HPA systems?

That's about the only conceivable way you can get air to stay in the valve. If you are unscrewing/turning off your tank, shooting out the last couple shots of air, THEN pulling the trigger to push the on/off pin back in, you should not have any residual pressure in the valve.

There is something wrong with your valve and it needs to be looked at by someone that knows what they're doing.

I, like Tunaman, have yet to have an on/off pop out of a valve in my countless years of working on hundreds of Mags.

As for the person that said the QD would wear out in my setup, you're wrong. That's what a quick disconnect is for. Turn off the tank, shoot out the remaining, shots, pop the QD and bleed the air. It's that simple and is fail proof.

[Skoad]

i have a classic valve and never had that problem. i just turn off my on/off, shoot until it stops cycling, unscrew the tank.


nothing has ever shot out of my valve

[LoveMyMagMoreThanYou]

I not only have a QD I have a bleed valve. I have not had the problem that has been described happen to me I just saw somewhere that pressure can remain in the chamber with the LX setup.

[LoveMyMagMoreThanYou]

Ooops, I meant slide check

[Dave]

BlackVCG,

The issue of having a check valve in the fill nipple is the original problem I had the the on/off shooting out at me. When I was getting my mag setup in the pro shop, the gut handed me a fill nipple with the check valve in it (at the time I had no idea what it was or what it did) and I asked him if it would cause any problems, and he say NO

That issue was not related to LX, and since the check valve was removed, I've had no problems with that valve.

However, with my other valve, the one with LX, this problem also occurs. No, it doesn't have a check valve in it, I know exactly what your talking about. I STRONGLY believe this issue is connected directly w/ LX.
