This small and space-saving float valve is designed to efficiently regulate water output compared to traditional models. It features a ball float mechanism that allows water to flow until a preset level is reached. As the water rises, buoyancy lifts the float, which automatically shuts off the water flow. When the water level drops, the valve reopens to resume filling, all without the need for electricity. Constructed from food-grade stainless steel, this automatic water level control valve ensures safe use with drinking water. The durable, corrosion-resistant material provides excellent strength, impact resistance, and longevity. The valve includes a built-in filter that must be installed at the water inlet to prevent debris such as sand or sediment from blocking the float mechanism. The entire unit is made of stainless steel, including the screws, ensuring rust-free and reliable performance. With a high melting point, this valve offers superior heat resistance, corrosion resistance, waterproofing, and fire resistance compared to standard ball valves. Ideal for use in water tanks, water towers, pools, solar water heaters, and storage systems, this valve operates using clean water pressure as low as 0.2 kg and requires no electrical power.
