Looking for water valve shutoff and stay off or stay on

[RickPowell]

I am trying to build a garden gadget that controls water flow to sprinklers and hopefully some other creations. I want to electrically trigger the valve to either be closed or to be open.

I like this product http://www.adafruit.com/products/997 which is normally closed, but I do not want to have to continually supply electricity to hold it open. I would like it to be open by default, and electricity would shut it off and keep it shut off after removal of electricity (kind of like an overflow safety). That would be good for starters, as long as I have a way to manually (or electrically) reopen it.

Ideally, does anyone know of a product that I can send a large pulse to that will either open or close a water valve (do the opposite state that the valve is in)? The lower the voltage/current requirement the better.

Many thanks in advance for links, advice, etc.

You want a DC latching solenoid.

Would a motorized ball valve work? I'm looking for the same thing and ran across these:

Wow - Thanks to both of you for lightning quick replies!
Either of these look like they could work for me.
Thanks again!
