Application
The Model F745X Remote Control Float Valve produced by our company is mainly installed in the water inlet pipelines of various water tanks and water towers in industrial enterprises and civil buildings. It automatically closes when the water tank reaches the preset water level and opens automatically to replenish water when the water level drops.

Features
1.Tight and reliable closure: Equipped with a robust rubber sealing ring, it adopts the hydraulic control principle, making the sliding plate closing force proportional to the water pressure for high sealing reliability.
2.Large flow capacity: The valve body features a full-channel streamlined design, ensuring low fluid resistance and large flow rate.
3.Easy operation and maintenance: The main valve is installed outside the water tank, enabling convenient commissioning, inspection and simple maintenance.
