1. Purpose: Water level control for water tanks/water towers/water reservoirs.
2. Working Principle: When the water level in the tank drops, the float ball descends. Utilizing the water pressure inside the pipe, it opens the sealing silicone-faced plunger inside the valve body, allowing the valve to open and supply water. When the water level in the tank rises, the float ball ascends. The connecting rod drives the plunger, causing the silicone body to seal the water inlet hole, thereby stopping the water supply.
