This valve is provided with a 220V electromagnatic control valve on the base of an ordinary filter piston remote-control float valve for dual assurandce. Under normal working conditions, electromagnetic control valve starts when connected to power, and works at the same time with filter piston remote-control float valve. Only filter piston remote-control float valve performs the function of control. Besides, the cutoff of power supply will lead to power failure of electromagnetic control valve, and main valve will close. After power supply resumes, filter piston electric float valve will continue to work in good condition.
Float valve is usually separately mounted from main valve body.
