Ball Float Valves

A ball valve is a manually or actuator-operated valve using a rotating ball to start or stop flow through a pipe. A float valve uses a buoyant ball that rises and falls with liquid level to automatically open or close a valve mechanism, making it a self-regulating device for level control rather than direct flow shutoff.

A floating type ball valve refers to a float ball assembly, typically stainless steel, that floats on a liquid surface and mechanically or magnetically triggers a valve or switch as the level rises or falls. It's commonly used in tanks, sump pumps, steam traps, and vacuum systems for automatic level regulation.

Float balls are most commonly manufactured from 304 stainless steel, with 316 stainless steel available for corrosive or high-purity environments such as chemical processing. Other materials can be sourced upon request. Stainless steel offers superior durability, pressure resistance, and longevity compared to plastic float alternatives.

Yes, float balls can be tapped with virtually any thread specification, including NPT, UNC, and custom sizes, along with through tubes, hooks, and magnet integration. This allows the float to connect directly to valves, rods, or measurement devices for seamless integration into existing liquid control systems.

Round float balls are commonly available from 1-1/2" up to 14" in diameter, while oblong floats range from small 2 x 6" designs to larger 9 x 14" configurations. Custom sizes and shapes outside standard inventory can also be manufactured to meet specific tank or valve requirements.

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