The single station, battery operated controller with LCD display and 3/4 in inline valve is recommended for any low to high flow system. The controller has a 3/4 in female pipe thread (FNPT) inline valve and an operating flow range of 0.1 to 28 gpm. Adapters are included for converting the inline valve with pipe thread into hose thread. We recommend using the controller with drip irrigation, sprinkler systems or any other watering application that requires more than 6 gpm or 360 gph.
