Float & Check Valves

A ball float check valve combines both functions: a buoyant ball float rises or falls with liquid level to seat against an orifice, sealing it to prevent backflow or overflow once a set level is reached. It's commonly used in vacuum tanks, sump pumps, and steam traps to provide automatic shutoff without external power or controls.

Our float balls are manufactured primarily from 304 and 316 stainless steel, chosen for corrosion resistance and durability in harsh industrial environments. 316 stainless steel is typically selected for applications involving corrosive chemicals or saltwater exposure, while 304 stainless steel suits general industrial and food-grade uses. Other materials are available upon request.

Yes, our float balls can be fitted with custom magnets for precise magnetic level detection, as well as custom thread specifications, fittings, or through tubes to match your existing rods or measurement devices. Common thread options include 1/4-20, 3/8 NPT, 1/2 NPT, and 3/4 NPT, with additional specs available on request.

We offer round float balls ranging from 1-1/2" to 14" in diameter, as well as oblong floats in sizes such as 2 x 6", 3 x 5", 7 x 12", and 9 x 14", among others. Custom sizes and shapes outside our standard inventory can also be manufactured to meet specific system requirements.

Yes, all float balls can be pressure tested using our in-house equipment to meet customer-specified pressure ratings before shipment. This ensures reliable performance in high-pressure environments such as vacuum tanks, steam traps, and industrial process control systems where failure isn't an option.

Yes, we ship directly to customers worldwide with a large ready-to-ship inventory of common sizes to minimize delivery times. For custom orders, lead times vary depending on specifications, and our team can provide accurate shipping timelines upon request at (416) 805-8132.
