Not for a permanent installation. The valve isn't used enough to stay healthy, and if it fails, you can't do anything about it (at depth). The fewer moving parts, the better.

It is not like I can get out to shut it off in the water if it is leaking.  I fill the tank from my onboard air compressor, so there is no need to remove the tank.  I have a shut off valve inside the hull at the penetration.  Any thoughts
