At the entrance of the valve installed in the pool or water tower, when the water level reaches the set release degree, the main valve by the float pilot valve control to close the water inlet to stop the water, when the water level drops, the main valve by the float pilot valve switch control to open the water inlet to the water into the water supply, automatic replenishment.
Precision from the valve control, not disturbed with water pressure, can be arbitrary installation location, reliable sealing performance, installation, maintenance, debugging, checking convenient, long service life (floating ball valve can be installed from the main valve).
