While I like your ideas, I think you may be over-complicating things.

Here's my first thought:

(Apologies for the half-assed sketch.)

That's definitely a good idea. Especially for gravity feed. Somehow that eluded me entirely hahaha. Probably need a pretty high current depending on the fluid volume though. I'll have to sit down and come up with some other ideas too :).

It shouldn't be too difficult to come up with other solenoid-type arrangements. I'll see if I can come up with or something better and suitable for other orientations. I had been thinking about how to make valves with <a href="http://en.wikipedia.org/wiki/Nickel_titanium" target="_blank">nitinol</a> <img src="../scipics/_wiki.png" /> <a href="http://en.wikipedia.org/wiki/Shape_memory" target="_blank">shape-memory alloys</a> <img src="../scipics/_wiki.png" /> for a few days, but haven't come up with anything worth posting yet. There are already some commercially available.
