Valve search 1

[Shaw60]

I am looking for a valve that would allow submerging a buoyancy ring in sea water by feeling a cavity. Any idea of the kind of valve I need to use and where could I get it?

Thanks

Peter

You mean a valve that will pass gas, but stop liquids?

You need an anal sphincter valve.

You're sitting on one. ;-)

They are not produced commercially.

Seriously, please tell us just a little more about what you're trying to do, so maybe we can translate it into words that we understand. Thanks.

I am really sorry for not making myself clear.
I need to submerge and surface a cage equipped with ballast compartments. I have read that to fill the balancing tanks I could use something called a Kingston valve but I cannot find anymore information about these kind of valves or where to get them.
Is that a bit clearer?

Thanks

Peter

Here's a definition:

This illustration is not very illuminative on my browser:

This explains how they are used:

For military use, the ballast tank valves must be large and/or numerous. For civilian applications, flow rate is not so critical, but you still want something simple enough to be robust and to be relatively insensitive to biofouling whether held open or closed for long periods. Low leakage is also a good thing. Rubber diaphragm valves might be a good choice.
