Applications

Tips: Working principle of water level control float valve
The water level control float valve works in conjunction with the main valve and the control float valve to realize automatic water supply and water cutoff of the water tank. The upper chamber of the main valve is connected to the float valve, which is installed at the liquid level of the water tank to sense water level changes and control the main valve switch.
When the water level in the water tank drops to the set position, the float valve opens, causing the main valve to open and water to start being supplied to the water tank; when the water level rises to the height set by the float valve, the float valve closes, and the main valve closes synchronously, stopping the water supply. The entire process does not require external power and is automatically adjusted by water level changes to ensure that the water level in the water tank remains within the set range.
