Q:

leaking high flow valve

Hallo,

My selph valve is leaking since I put a new stem in it. I checked the valve seal to see if there is a piece of grit or something on the sealing face which would cause the leakage, couldn’t find anything. After assembling the same result: hissing sound and a little air comming out of the tophat.
How do I get this thing fixed?

What it means is that the hole in your valve might be at the top of tolerance and the stem (having been made by a third party I assume) is closer to the bottom side to make shure it fits and has the best chance of working but because the seal is allowed to hit the valve face crooked because of the slop and therefore not sealing all the time ..so what I would do is get in touch with who ever made the new stem for you and explain what is going on and see if they can make you another one but send them the valve body too so they can make it fit with little “wiggle” room….Greg

is their “slop” in the valve stem??….ie you can wiggle the valve stem in the guide..

I just cheched it and probably you’ve got the right answer to the problem. I can wiggle the stem a little bit. So does that mean that the stem is of no use in my valve? 😯

Thanx guys, but I tried that already and it doesn’t work. The strange thing is, sometimes it stops leaking for a few shots and then it start to leak again and doesn’t stop anymore. Can’t think what it is or how to solve it. And that’s a shame cause I realy like to shoot that valve, more consistent then anything else.

a few dry fires should help the valve seat its self…

I am not positve on this but I thought I seen some post on that a while back, if you take a few shots with the tank filled it will seat itself and stop leaking, like I said not 100 % this is what I read but won’t hurt anything 😯
