Automatic Water Level Control Without Electricity
The Automatic Plastic Float Valve provides a simple and reliable solution for maintaining water levels in tanks, reservoirs and storage containers.
The valve operates through a mechanical float mechanism and requires no electricity, external controller or manual operation. As the water level rises, the internal float mechanism closes the inlet automatically. When the water level falls, the valve reopens to refill the tank.
The product is available with side inlet or top inlet configurations and multiple connection sizes, making it suitable for different installation requirements.
With a lightweight plastic body, compact structure and simple installation, the valve is suitable for domestic water tanks, livestock troughs, agricultural water systems, reservoirs and other clean-water applications.
Its automatic shut-off and refill function helps reduce overflow, minimize water waste and simplify water level management.
