First of all, sorry for resurrecting this topic. I know this is an old discussion, but I do have a doubt that fits here, let me explain.

I recently moved from Brazil, were I was team RioBotz (Touro, some of you might know) captain. Since robot combat is highly addictive I decided to build a new robot to compete here in the UK, in Brazil and USA, at the Robogames. The only common class among these locations is 30Lbs Featherweight, and since the distances involved are huge, there wouldn't be any reason to build a heavyweight (We already have Touro Maximus in the US).

The problem:

I am designing a full pressure CO2 flipper, and read all the forum topics (really it took me months to do so) and rules, which by the way is really good concerning pneumatics. Researching about SPRVs I came across the Wizard of NOS valve (factory setted to 1000PSI), witch is intended to replace burst discs on NO2 bottles and one thing that always scared me was the possibility, even tough minimum, of a burst disc failure, such as presented in the following link:

http://forum.nitrous-advice.org/view...t=4025&start=0

When burst discs fail the whole content of the bottle is released, producing a dangerous situation if the bottle is being handled at the time, that can result in severe cold burns. I know that burst discs rarely fail, but they aren't fail proof, specially on an aggressive environment, such as combat arenas.

So the question is, can this specific valve be used in place of a burst disc?

If negative, can it be used at all?

I've already talked with Dave Calkins (Robogames Chairman) and Paulo Lenz (RoboCore Brazil Chairman) about the project and both gave me their blessing, although I will have to fit a gauge to compete overseas... Useless, I know, but it is the only point of the RFL rule that I failed to convince them.
