If you use motorized ball valve, the 2-wire auto-return is probably the simplest to work with, as it should be able work with OpenSprinkler without modification. The 3-wire or 2-wire reverse polarity both requires either hardware or software modifications. On the link you posted, CR04 seems to be the 2-wire auto-return type.
