If you are looking for information on the battery-operated underground timer that Orbit offers, then this article should have some helpful information.
(57869) – Any plastic Orbit valve will work. You will need to replace the existing solenoid with the 57869 solenoid. The 57861 comes with a rotational adapter – if the existing solenoid/valve doesn’t use a rotational adapter, you should remove it from the 57869, and if it does come with one, you can use the one on the 57869, or the one on the valve. Leaving the rotational adapter on when not needed could cause the 57869 to not fit perfectly on the valve.
(57869) – One timer can control up to 4 valves.
(57869) – It uses 3 double-A batteries.
(57869) – To locate the timer away from valves, solenoid leads can be extended up to 100’ by cutting solenoid wires and splicing in the amount of 18-gauge wire that’s needed.
