H142X hydraulic water level control valve

H142X hydraulic water level control valve is a water control valve which can automatically control the liquid level of water tank and water tower. When the water level drops more than the preset value, the ball valve opens, the chamber pressure on the piston decreases, and a pressure difference is formed between the upper and lower parts of the piston. Under the effect of the pressure difference, the valve disc opens for water supply operation; when the water level rises to the preset height, the ball valve closes, and the chamber pressure on the piston increases, which makes the valve disc close and stop water supply. In this way, the liquid level setting height can be automatically controlled to realize the automatic water supply function.
