Comment on Vigoro 3015V Sprinkler Timer Internals and Valve Design by Jon-A.
I called Orbit and they said to just reverse the polarity. 3v DC is the amount they said to use to open it and then just reverse the polarity to close it. The open part works but not the close. I am trying to control this through a parallax basic stamp controller. For now I am just directly making the connections to open it and close it. The close when attached to the timer has a little bit of a delay, but closes just fine. When I open it by applying volts, I have to reattach to controller to close it. Any thoughts or ideas you come up with would be greatly appreciated. Thanks!
