Here’s how I converted my old orbit sprinkler irrigation valves to the new batter powered solenoids for us with their battery powered irrigation sprinkler timer.
FYI, at least for anybody else who found this, the Orbit part # for the timer + valve kit shown here is 57860 while the individual DC solenoid is 57861. The timer by itself is 57865
Were you saying you never had electricity in the valve box out there? Then how did you power the old A/C solenoids before replacing them with the new battery operated D/C ones?
