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...
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
