The 106X remote controlled solenoid ball float valve is a valve that has a constantly open (or constantly closed) solenoid control unit installed on the 100X remote controlled ball float valve. This configuration bears a double safe function, i.e., the water level can surely be controlled below a preset elevation even if a power outage occurs or the electric ball float malfunctions. The On/Off level of the electrically driven ball float valve can be set to solve the frequent turning on/off of the main valve. This valve can be widely used in influent pipes of the pools and water towers in high-rise buildings, municipal domestic water systems, fire fighting facilities, factories and mines.
