H142X hydraulic water level control valve is a hydraulic control valve that automatically controls the level of water tank and water tower. When the water level drops more than the preset value, the float ball valve is opened, the pressure of the upper chamber of the piston is reduced, and the pressure difference between the upper and lower piston is formed. Under the action of this pressure difference, the valve disc is opened for water supply operation. When the water level rises to the preset height, the float ball valve is closed, and the pressure of the chamber on the piston is increasing, causing the valve disc to close and stop the water supply. Such reciprocating automatic control of the liquid level at the set height, to achieve automatic water supply function.
