H142X hydraulic water level control valve is a hydraulic control valve that automatically controls the height of water tank and water tower.When the water surface drops more than the preset value, the float valve opens, the pressure in the upper chamber of the piston decreases, and a pressure difference is formed between the upper and lower piston. Under the action of this pressure difference, the valve disc opens for water supply operation.When the water level rises to a preset height, the float valve closes, increasing pressure in the upper chamber of the piston causes the disc to close and stop the supply.This reciprocating automatic control of liquid level setting height to achieve automatic water supply function.
