 Alec, thanks for the inspiration.  Watching your sub sink is just friggin amazing.  The air cylinders are double acting and will be spring loaded to stay closed.  The air pressure will open them with a permanent air leak via a tiny drilled hole like you have.Hank

 Now that is clever, I never thought of moving the whole valve instead of just a lid, and it sure simplifies things! Are those actuators NC though, or can they be made so? Just so you don’t need HP in order to stay on the surface. 

Thanks,
Alec
