Ok....I can't believe I'm even seeing this thread about "
Burst Diaphragms " and " scuttle valves".....There is no reason that
any one would ever need to open up a pressure vessel to the sea let
alone that it could possibly occur when it would be a total
surprise....this is a joke ,,,right.. Think about it,,a one inch
burst disc at 300 PSI....We spend a lot of MONEY and TIME figuring out
how to keep the water out.

more water sending you down faster etc. etc. Not a good idea!
A scuttle valve is just as it implies. For scuttling the sub as a
very last
resort. Anything else that lets water in the sub would also be a
very last
resort valve and you better be prepared to exit because your
probably not
going to see the surface looking through the viewport again.
