The 100X remote controlled diaphragm-type ball float valve is a multifunctional waterpower operated valve. It is mainly installed at water inlets of ponds or elevated water towers; when the water level reaches a preset elevation, the main valve stops water supply under the control of the ball float pilot valve; when the water level drops, the main valve, controlled by the ball float switch, opens the water inlet to inject water into the pond, thereby realizing automatic water replenishment; the precision in water level control is high and is not affected by water pressure; the 100X remote controlled diaphragm-type ball float valve can be installed freely to suit the elevation of the pond and the space of use, is convenient to maintain, debug and inspect, reliably sealed and long in service life. This diaphragm-type ball float valve boasts reliable performance, a high strength and agile actuation, and is suitable for use with pipes of a caliber below 600mm. Valves of a piston type are recommended for applications involving pipes of a caliber above DN600mm.
