This product is compact and space-saving, designed to improve water output efficiency compared to traditional models. It features a ball float valve that allows water to flow until a preset level is reached. As the water rises, the float valve lifts due to buoyancy, automatically shutting off the water flow. When the water level drops, the valve reopens to allow refilling, operating entirely without electricity. The stainless steel automatic water level control float valve is constructed from food-grade stainless steel, ensuring safe contact with drinking water. It has a durable, hard-shell design with excellent resistance to friction and impact, enhancing product longevity and reliability. The valve includes a built-in filter that must be installed at the water inlet to prevent sand and debris from obstructing the float mechanism. The valve body and screws are made of stainless steel, providing rust resistance and long-term safety. Compared to other ball valves, this model offers superior temperature tolerance, with high heat resistance, corrosion resistance, waterproof performance, and fire-resistant properties. It is suitable for various applications including water tanks, water towers, pools, solar water heaters, and water storage systems. It operates without electricity and requires clean water with an inlet pressure above 0.2 kg to function properly.
