Stainless Steel Float Balls for Float Valves

Most float balls are manufactured from 304 stainless steel, the most common and cost-effective option, or 316 stainless steel for enhanced corrosion resistance in chemical or saltwater environments. Other materials are available upon request for specialized applications requiring specific chemical compatibility or temperature tolerance.

Round float balls are available from 1-1/2" up to 14" in diameter, while oblong floats range from 2 x 6" up to 9 x 14" with various thread options like 1/4-20 and 3/4" NPT. Custom sizes and shapes outside these standard ranges can also be manufactured to match exact system requirements.

Yes, float balls can be manufactured with custom magnets installed inside for precise magnetic level detection, as well as custom threads, through tubes, hooks, and other fittings. These customizations allow the float to integrate directly with existing valve assemblies, sensors, or measurement devices without additional adapters.

Yes, float balls can be pressure-tested using dedicated testing equipment to meet customer-specified pressure ratings. This ensures reliability in high-pressure environments such as vacuum tanks, steam traps, and industrial process vessels where float integrity is critical to safe and consistent operation.

Stainless steel float balls are widely used in food processing, chemical manufacturing, wastewater management, and industrial process control, including vacuum tanks, sump pumps, and steam traps. Their corrosion resistance and durability make them suitable for monitoring liquids ranging from oils and syrups to corrosive chemicals and treated wastewater.

Round float balls provide uniform buoyancy and are commonly used in standard float valve and level detection applications. Oblong floats offer a larger surface area and different buoyancy characteristics, making them well-suited for applications requiring more stable positioning or specific tank geometries, such as narrow chambers or through-tube installations.
