Function and benefit Automatic, power-free water level control for tanks, towers, pools, reservoirs, solar water tanks and other water storage. Works with clean water at a connected pressure of more than 0.2 bus to maintain the desired level without electricity or manual intervention. Prevents overflow and dry run by reliably opening and closing based on water pressure and level, reducing maintenance and water waste. Key features Material: Valve body constructed from 304 stainless steel (food-grade 304 stainless steel). Durable, corrosion-resistant, and safe for potable water. Compact design, high flow: Small physical size that saves space while providing larger displacement and higher water yield than conventional float ball valves. Robust housing: Hard shell resists friction and impact to extend service life. Temperature and environment: Better high-temperature resistance, higher melting point, corrosion resistance and waterproof/fire-resistant properties compared with other stainless-steel float valves—suitable for a wide range of ambient conditions. Why customers choose this product Reliable no-electric solution for water level control in remote or off-grid locations. Longer-lasting construction lowers replacement and maintenance frequency. More efficient filling performance than standard float ball valves, improving water supply speed and system responsiveness. Typical applications Rooftop or household water tanks and water towers for automatic filling and overflow protection. Solar water heating tanks where electrical control is not available or desirable. Pools, small reservoirs and agricultural water storage where durable, food-grade materials and high flow are needed. Practical notes Designed for clean water systems and requires a connected pressure of more than 0.2 bus to operate correctly. Choose this valve when space is limited but higher water yield and longer life are required.
