The LEMA 1700S solenoid actuator is designed to be used in conjunction with the LEIT system including LEIT 4000, LEIT X and LEIT XRC ambient light powered controllers. It is an encapsulated, watertight, two-way magnetic solenoid actuator that requires minimal power to operate with the LEIT 4000, X and XRC series controllers. Once the original solenoid is removed, the LEMA 1700S solenoid actuator can be installed with one of our seven adapters, allowing conversion of most brand name valves.
