LEIT 1 Manual Valve Actuator

DIG’s LEIT 1™ single-station solar powered controller with an actuator is used to retrofit a 3/4” or 1” manual anti-siphon 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 used 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.
