55295 E-CHEMSAVER® MAINTENANCE INSTRUCTIONS
The 55295 e-ChemSaver is a solenoid-actuated shutoff compatible with a wide range of TeeJet nozzle bodies equipped with a diaphragm
check valve. It can be used for end-of-boom nozzles as well as individual nozzle shutoff and PWM controls.
The valve is normally closed and opens when the solenoid is energized. The 55295 has a 2-pin MetriPack connector molded into the body for
a clean, weather-tight electrical connection.
