if you heat them up to soldering temperature's you wont ruin the seals ,you will however loosen them up and form the seals to the ball as opposed to wearing them in
a few minutes over a homes gas stove would make the your problem go away.
heating them is also the only way I know of taking them apart without damaging them
I noticed that regular solder ball valves seem to be looser yet hold the seal after they have been heated up so I was wondering about that. I just wanted somebody else to mention it backing my hypothesis up before I went and did it.
So about 30 minutes ago I just heated the sucker up with a propane torch for a few minutes and open/closed it a few times and presto! Now there's almost no resistance and it still holds the seal.
Well there you go MrCrowly, if you haven't already, you can do that and most likely it will loosen up your ball valve too
Thanks again cdheller!
