F745X remote control float valve is an underwater operated valve with multiple functions. It is mainly installed at the water inlet of the pool or elevated water tower. When the water level reaches the set height, the high valve is controlled by the float pilot valve to close the water inlet to stop the water supply; when the water level drops, the main valve is controlled by the float pilot valve to open the water supply. The water port injects water into the pool to realize automatic water replenishment. The liquid level control is precise and free from water pressure interference; the diaphragm type remote control float valve can be installed at any position according to the height of the pool and the use space, which is convenient for maintenance, debugging and inspection, reliable sealing and long service life. Diaphragm valves are reliable in performance, high in strength and balanced in action, and are suitable for pipelines with a caliber below 450.
