Compact, space-saving design: smaller footprint improves water flow performance and delivers higher discharge efficiency than many traditional float valves. The compact size increases usable water capacity without sacrificing control. Automatic shut-off (Auto stall off): a springless, mechanical system where the float rod activates the piston. As the water level rises the piston closes the valve using pipe pressure; when the level falls the valve reopens. This provides reliable, hands-free water level control and consistent fill performance. Food-grade 304 stainless steel construction: the valve body and shell are made from 304 stainless steel for corrosion resistance and long service life. The sturdy shell improves durability and resists wear in demanding environments. Low-temperature and high-temperature resistance: stainless steel components and a heat-resistant shell reduce the risk of rot and degradation. The valve is designed to tolerate a wide range of operating environments and offers waterproof and fire-resistant properties for added reliability. Practical performance features: engineered for efficient discharge, stable water-line control, and repeated cycling without performance loss. Uses water-pipe pressure for valve activation, minimizing external power or auxiliary controls. Where it’s useful: Livestock and poultry watering systems — consistent water levels and durable materials reduce maintenance and contamination risk. Domestic and commercial water tanks — compact form factor allows installation in limited space while maximizing tank capacity. Industrial process, cooling, and irrigation systems — dependable automatic control and corrosion resistance make it suitable for continuous operation. What you get: a compact, food-grade 304 stainless steel float valve that replaces traditional float valves to improve discharge efficiency and water capacity, automatically controls water level via float-rod/piston action, and withstands challenging environments. Compatibility note: designed to perform the same valve functions as conventional float valves, using supply-pipe pressure and the float-rod-driven piston mechanism for automatic operation.
