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 is lifted by buoyancy, automatically shutting off the water flow. When the water level drops, the valve reopens to resume filling, operating entirely without electricity.The stainless steel fully 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 debris such as sand or gravel from obstructing the float mechanism. The entire unit is made of stainless steel, including the screws, providing rust resistance and long-term safety.Compared to other ball valves, this model offers superior performance in high-temperature environments due to the high melting point of stainless steel. It is resistant to corrosion, waterproof, and suitable for various conditions.Ideal for use in 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.Specifications: Type: B-1/2 inch side inlet / C-1/2 inch top inlet / D-3/4 inch top inlet / A-3/4 inch side inlet Applicable temperature: 0–100°C Working pressure range: ≤ 1.0 MPa Residential tap water pressure: 0.3–0.5 MPa Pressure range: 0.2–10 kg Medium temperature: ≤ 1–80°C Material: Stainless steel Color: Silver Package Contents: 1 x Blow-off valve Note: Lighting and display settings may cause slight color variations in the product image.
