Material and water quality The float valve is made of ABS material with a firm surface structure. It produces no odor when in contact with water, helping to keep water quality unaffected. Automatic water control Equipped with a floating ball linkage mechanism, the valve automatically shuts off when the water level reaches the threshold and resumes supply when the level drops below the minimum threshold, providing automatic water control. No power required The valve operates purely mechanically, driven by buoyancy from water level changes. No power source is needed. Easy installation No specialized tools or installation experience are required. Simply align the valve with the water tank inlet, use the included accessories, and tighten to secure. Practical use scenarios Domestic water storage: install in a household water tank to prevent overflow while maintaining a continuous supply. Garden irrigation: use in a reservoir or tank for automatic up to support drip irrigation or sprinkler systems without pumps. Livestock or pet water troughs: maintain a consistent water level with automatic shutoff and refill, reducing manual checks.
