THose weren't off anyone's shelf. They are essentially cartridge valves operated internally with air at 3000 psi. Solid stainless, and the things must weigh ten pounds apiece. But they simply don't fail, and even if a leak appeared, it would be a quick and easy overhaul which could easily be done right on the tank. That's hard to beat, operationally.

There are a variety of pneumatic valves available off the shelf. The JSL subs use them.

Hi All,

=0 A

 I recall someone having a smart design for a vent valve operated by a small Air Cylinder.  Can anyone remember where the sketch was.  I think it was about a year ago.  I’ve tried the Search although admittedly not persevered too long.  Chs Hugh
