Product Presentation:

The valve consists of the main valve and outside installed pilot valve. I uses the float in the water to link the pilot valve upon the change of the water surface to make the main valve supply water or be closed., thus to contol the waterlevel of the water pool and the water tower within certain limits.

This series of valve products are widely used for level control of the towers, pool and other facilities, high-rise building, living area and the water-supply systems. The body uses full passage streamline design, of a heavy flow, a good sealing effect, a high liquid level control accuracy, simply maintained, flexible and durable, the water level is not subject to the water pressure disturbance and tightly closed without water leak. The upper cavity of the main valve is connected with the controlling floating ball valve. The floating ball valve is fixed on the liquid level of the water tank and will be opened, when the liquid level lowers, then the main valve is opened to supply water to the water tank; when the liquid level rises to the position where the floating ball valve stays at, the said valve is closed and so is the main valve, stopping the water supply.Characteristics: The body uses full passage streamline design, of a heavy flow, a good sealing effect, a high liquid level control accuracy, simply maintained, flexible and durable, the water level is not subject to the water pressure disturbance and tightly closed without water leak.

Principle:
The upper cavity of the main valve is connected with the controlling floating ball valve. the floating ball valve is fixed on the liquid level of the water tank and will be opened, when the liquid level lowers, then the main valve is opened to supply water to the water tank; when then liquid level to the position where the floating ball valve stays at, the said valve is closed and so is the main valve, stopping the water supply.
