Howdie!

Alright, I got a problem w/ DIN valves.  I've been following the thread thread
(hmmm)  anyway, I didn't get exactly what I was looking for from that.  My
problem:  I'm looking for real live 300 bar DIN fittings, and I don't know 
what to look for.

Info I've gotten so far:

I have Scuba Pro Modular valves, they are marked 232bar, but the SP rep says
they will do 300 bar if I replace the burst disks.

However, looking at them, they appear to be much shallower than 300bar valves
I've seen before.

So, 1st question - is it the inches of thread that determins the bar rating
of the valve, or the deepness of the thread cut?  I could see it either way.
But specifically, I was interested in the SP modular valves.

Secondly, I've got Scuba Pro Mk15 first stages that are DIN.  Their literature
says its a 300 bar reg.  However, again, the threads are shorter than other
300bar fittings I've seen, although the threads are very deeply cut.

Is there a way to tell just from looking?  Is there a spec (must be!) and if
anyone knows it, or could tell me where to find it, I'd appreciate it.

Thanks!
