The Plastic Top Inlet Solar Magnetic Automatic Water Level Control Valve is a fully automatic float valve designed for water tanks, water towers, reservoirs, and solar water supply systems. Using magnetic float control technology, it automatically stops water flow when the tank is full and resumes filling when the water level drops. No electricity is required, making it energy-saving, safe, and reliable for long-term automatic water level control. The top inlet structure is suitable for vertical water inlet piping systems, while the PA66 nylon valve body provides strong corrosion resistance, temperature resistance, and long service life.

Equipped with a dual filtration system and enlarged water inlet filter, the valve helps provide cleaner water flow and improved anti-blocking performance. The screw-free buckle housing allows easy disassembly, cleaning, and maintenance. Available in internal and external installation versions with multiple size options, the internal type is installed directly inside the tank or water tower, while the external type is mounted outside and connected through a hose for synchronized water level control.
