Equilibrium Ball Float Valves

Float valves come in several configurations, including direct-acting, pilot-operated (equilibrium), and lever-arm designs. They also vary by float shape (round or oblong), material (stainless steel, plastic, brass), and mounting style (threaded, through-tube, or magnetic). Each type suits different pressure ranges, tank sizes, and liquid characteristics such as viscosity or corrosiveness.

Our float balls are manufactured in 304 and 316 stainless steel, chosen for corrosion resistance and durability in demanding environments. 316ss offers enhanced resistance to chlorides and corrosive chemicals, making it ideal for wastewater treatment and chemical processing, while 304ss is a cost-effective option for general industrial and food processing applications.

Yes, float balls can be custom-tapped with virtually any thread specification, including NPT, UNC, and metric options, plus custom fittings, through-tubes, and magnet integration for precise level sensing. This allows each float to integrate directly into existing valve assemblies, level switches, or measurement instrumentation without modification.

Round float balls range from 1-1/2 inch up to 14 inches in diameter, while oblong floats are available in sizes such as 2x6, 3x5, 7x12, and 9x14 inches, among others. Custom sizes and shapes outside standard inventory can also be manufactured to match specific tank or valve assembly dimensions.

Yes, every float ball can be pressure-tested to meet customer-specific requirements before shipment, ensuring reliable, leak-free performance in high-pressure vacuum tanks, steam traps, and sump pump systems. Testing equipment on-site allows verification against exact application specifications prior to delivery.

With a large inventory of common round and oblong sizes kept in stock, most standard float balls ship quickly, with direct-to-customer shipping available worldwide for faster turnaround. Custom orders requiring unique threads, fittings, or magnets may require additional lead time for fabrication and testing.
