[PSUBS-MAILIST] Mushroom Valve?

[hank pronk via Personal_Submersibles]

 James,Since these are simply for stability, I would use two solenoid valves.  No need to weld into a finished sub.  I would make a container to put the valves in so they can be oil filled.  This is what  Elementary 3000  has.  You can make the solenoid housing so it is part of the tank so it looks good.  I like the deck idea also-Gamma has a deck and it is great.Hank

James,

  

The Drebbel has a lever operated 1 ½” ball valve. 

You could add a deck plate. This covers the valves, looks good with saddle tanks and is very usefull.

Hi All,

  

I am adding saddle tanks to Jodie B.   

  

Im not 100% sure what to do with regards to the vent plumbing.  I would like to ask if anyone has any advice?  

  

I am thinking of putting 2x through hulls on the top of the main pressure hull.  For and aft of the tower and then piping the vents to a valve that would operate through them.  Similar to the existing vents.

  

OR, fit the through hulls at the side so they penetrate the tanks and have a linkage of some sort that operates valves attached to the top of each tank, for and aft.  Some sort of mushroom valve??

  

Any ideas?  What have other people done?
