Hunter Node 4 zone / station battery operated sprinkler irrigation controller, comes with 3 of the DC latching solinoids.
as far as I know will only work with Hunter valves, might be a solinoid adapter made for other brands of valves, or the solinoids will fit any brand of valve....just not sure on that.
uses 1 or 2 standard 9 volt batteries. must use DC latching solinoids, regular sprinkler solinoids will not work.
