this look similar to the design i'm currently working on, which is based on the blastfire, except the my design would use multiple barrels, each with a valve, like the blastfire.

and i agree that the two valve sytem would work better, and take less tinkering than this system. the fact that there is a stage where the valve is completely open is the problem, because you rely on the speed of the hose trigger to keep all you pressure from rushing out. if you want a valve without this problem, why not just use the semi-auto valve by zero, in the mods section of this very site :

ok, i know that you just wanted a critique of a new idea, but if you're trying to build a gun there you go.

and it would be awesome if you actually got a valve like that to work, despite all the doubters have said.

thats exactly what i needed. thanks a lot. the prtotype valve needs some fine tuning but that more or less exactly what I needed. thanks!
