[PSUBS-MAILIST] Snorkel

[Emile van Essen via Personal_Submersibles]

Mark, All.

Mind the area is big enough. The valve in the attachment is designed for a
3000 Kg sub. But even then it is to small if you surface too quick in case
of massive overpressure.
Cracking pressure: 25-75 mBar.


Best regards, Emile

Since we are discussing over-pressure valves, can you recommend a make and
model, or describe its specifications? 

Regards,

Mark...
