I was thinking of using a tension sping to open a ball valve quikly. Please let me know what you think and give me some latch ideas.

Hmm...
Do you mean so that it opens easier? because if the spring itself opens it, then during refilling one has to keep their hand on the valve handle. I was thinking of something very similar to this, but ruled it out because of that. Instead I just use the thumd on my left hand to assist, once I get my homemade working again. Solenoids operated valves, however costly they are, are pretty much the best choice for a quickly opening valve. As for a latch, what kind of valve handle? If it has a plastic double wing design, just drill a hole and hook up one end of the spring to it. If it has one handle, I guess the same thing, except it's metal, so use of a stronger bit and more powerful drill is needed.

I have a double wing valve. I was going to have a latch that keeps the valve closed after you cock. I was thinking of a bar tha runs forwards from a hinge and has another part going down so you can make the bar swing down and allow the bottom wing of teh valve to go backwards.

I kinda see what your talking about. This is what I think you put, only in my words: A rod that prevents the valve from being opened, allowing the gun to be refilled. It would be attached to the valve by a hinge, allowing it to swing out of the way. So essentially it could double as a safety. Hmm. Interesting.
