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

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