I'm looking to control he flow of water between two tanks and am looking for
an Electric Valve to be able to shut off the flow to one of the tanks.

There could potentially be no pressure on the inlet of the valve until the
pump gets the water up to it. Though I don't see that as too much of an
issue as if there is a bit of water that goes to a tank that does not need
it, it should be okay...

Sprinkler valves are really cheap. Might do the job
depending on application and setting. If you need
something more durable, it might be worth building
a (disposable) prototype based on such a valve just
to get the design/specs right before constructing
an industrial strength version.

You need to think about the pressure and flow rates
you require -- diameter of pipe and material etc.
Also what sort of power/voltage you'll be using for
the controller.
