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...

Any Suggestions?

Thanks,

You'd need to know a bit more about the application,
but for cost you won't beat a sprinkler (lawn) control valve.
High flow capability. 24V control.

They are "pilot-operated" which means you do need some
pressure present. They can be modified to use an external
pressure signal when source pressure isn't sufficient.

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.

You're not giving much detail, but for good quality solenoid valves of all
flavors, google "Asco"

Thank you all for your replies.

So a bit more. Here is a Diagram of the System:

The 2 valves that I'm looking for are for the 2 Tanks. The 2 Clear ones on
the top row.

We have a Well that will be supplying the water to the Tanks. It has a 1HP
Pump and 1 1/4" line. So what ever the flow that is... I'd love 24VDC,
though I know most are 24VAC. I can throw in a Relay that is not an issue.

Thanks!
