[PSUBS-MAILIST] Flush Mount Valves in MBT's

[Alan]

Hi Joe,
While thinking about the ballast valve, it occurred to me that
the drain pop up plugs found in modern bathrooms, are very
similar to what we want.

Hope that link came out OK. It was an image search on DRAIN POP UP WASTE
They would need to work upside down for our application, so they would be flush on the
inside of the ballast tank (eliminating an air trap) but extend a bit above the ballast tank.
Some models look like you could just stick an air line straight on to them, & with a spring 
In them, they would work.
There may be some model that is ideal.

I’ve been looking at various products on the Net, and from what I see, there doesn’t seem to be an off the shelf remotely operated valve that would install flush and fully vent the tank. What I’m looking for is a flush mount and a clean installation which eliminates the exterior tubing routed to the conning tower.
