LEIT 1 with Inline Valve
DIG’s LEIT 1™ ILV-XXX single-station solar powered controller with a DC latching solenoid is available on a 3/4” to 2” inline globe valve. Powered by a photovoltaic module with a patented microelectronic energy management system, the LEIT 1™ requires no batteries or direct sunlight to operate, and it is installed above grade in any location where there is ambient light. Distinguished among the LEIT-1™ features are 20 preset monthly historical Evapotranspiration (ET) programs for spray heads and drip irrigation with an editing feature that can be used as part of the controller programming.
