About This Product

The Stable Float Ball Valve is an automatic fill and shut-off valve designed for humidifier tanks, water tanks, and other water storage systems. When the water level drops, the valve opens to refill; when the set level is reached, it closes automatically — no manual operation needed.

With a stable float design and durable materials, it is a reliable choice for controlling water levels in a wide range of applications.
