This inexpensive homemade valve can be used to relief compressed air from a hull. I guess it is easy to modify for your specific purpose.

This is what is done on the floats (amas) of Corsairs/F-boats. My F-27 has one on each float near the front beam.


I have one per watertight compartment per float, six in total.
