Corrosion-Resistant Stainless Steel Float Valves

Round float balls are available in sizes from 1-1/2" to 14". Oblong floats range from 2x6" up to 7x16" and 9x14" with various NPT and thread fittings. Custom sizes beyond these standard dimensions can also be manufactured to your exact specifications.

Yes. Any thread specification can be tapped, including common sizes such as 1/4-20, 3/8-16, 1/4 NPT, 3/8 NPT, 1/2 NPT, 5/8-11 UNC, and 3/4 NPT. Through tubes compatible with 3/8" to 3/4" rods and custom hook or fitting configurations are also available on request.

Absolutely. Both 304ss and 316ss are food-grade compliant materials widely used in food and beverage processing. Our floats are available in brushed or fully polished mirror finishes that meet hygiene standards, making them ideal for monitoring liquid levels in tanks and vats containing oils, syrups, and other liquids.

Magnets are custom-sourced and assembled inside the float ball during manufacturing. As the float rises or falls with liquid level, the internal magnet triggers an external reed switch or sensor to activate a pump, valve, or alarm. Common applications include sump pumps, vacuum tanks, and liquid level detection in chemical and industrial systems.

Yes. We have pressure testing equipment available to test float balls to custom specifications, ensuring they perform reliably in high-pressure systems such as steam traps and industrial process control environments. Testing parameters are defined per customer requirements for complete peace of mind.
