Float Control Valve

Basic Information
The float controlled water valve controls the level of the water in the water tower or sink.
Features
1. Stable and reliable work, large flow;
2. Disc fast open and slowly closed, no water hammer impact;
3. Good sealing effect and long service life;
4. Install at any location along with the height of the water tank and the working space.
Principle
When the pipe supplies water from the inlet end, because the needle valve, ball valve and float ball valve are normally open, water enters the water tank through the micro-filter, needle valve, control room, ball valve and float ball valve. At this time, there is no pressure in the control room; When the water level of the water tower rises to the set height, the ball float closes the ball float valve, controls the indoor water pressure rise, pushes the main valve to close and the water supply to stop. When the water level drops, the float valve reopens, the water pressure in the control room drops, and the main valve opens again to continue the water supply, keeping the setting height of the liquid level.
Installation and Commissioning
Horizontal installation is preferred for remote-controlled ball float valve. The main valve and ball float pilot valve can be remotely installed as a whole. This valve is installed in the water system and debugged. The globe valve is opened. The main valve needle valve is opened for 2 to 4 rounds. The ball valve is fully opened. For specific use, please consult ZhengFeng Valve Group.
