Compact, automatic stainless steel float valve that improves water discharge efficiency and delivers reliable level control without increasing footprint. Key benefits Compact design: Smaller footprint increases water flow performance and discharge efficiency compared with traditional float valves, allowing greater effective water capacity without compromising control. Automatic water management: The float rod drives an internal piston to open the valve when the water level rises and close it as the level falls, providing consistent, hands-off filling and preventing overflow. Durable construction: Rigid outer shell and hard 304 stainless steel components provide corrosion resistance and mechanical strength for long-term, reliable operation. Waterproof and fire-resistant: Stainless steel shell tolerates high temperatures, resists thermal damage and faults, and provides waterproofing suitable for demanding environments. Reduced maintenance and downtime: Robust materials and simple mechanical operation minimize service needs and extend service life. Function and performance Operates purely mechanically: float rod → piston → valve; no electronics required. Compact form factor maintains or improves flow rates while saving space. Built to withstand repeated cycling and typical exposure in water systems. Suitable applications (examples) Domestic and commercial water tanks: automatic refill and overflow protection for cisterns and rooftop tanks. Agricultural and livestock water troughs: reliable, low-maintenance level control for animal watering systems. Light industrial and irrigation systems: consistent refill control for process tanks, irrigation reservoirs, and similar installations. Materials and compatibility notes Main components manufactured from 304 stainless steel with a sturdy outer shell for enhanced resilience. Designed to deliver the float valve function—automatic opening and closing driven by the float rod and piston—while fitting into standard float-valve installations. What it solves Eliminates continuous manual monitoring of water levels. Reduces overflow risk and improves usable water capacity. Lowers maintenance frequency thanks to corrosion-resistant materials and a simple mechanical design.
