15mm ball float valves rely on precision-engineered stainless steel float balls to regulate liquid levels in tanks, sump pumps, vacuum systems, and steam traps. Constructed from durable 304ss or 316ss, these floats support custom threads, fittings, and magnet integration for accurate, pressure-tested performance across food processing, chemical manufacturing, and wastewater treatment applications.






A 15mm ball float valve uses a spherical float to automatically control liquid flow based on level changes. As liquid rises, the float lifts and closes the valve; as it drops, the valve reopens. These valves are common in tanks, sump pumps, cisterns, and process equipment requiring automatic level regulation without electronic controls.
