Double Float Valves

Round floats offer uniform buoyancy and are ideal for standard vertical travel in tanks, while oblong floats provide a larger surface area for stability in tighter or shallower chambers. Both shapes are available in matte, brushed, or polished finishes and can be paired together within a double float valve for staged level detection.

Floats are typically made from 304 or 316 stainless steel, chosen for corrosion resistance and durability in harsh liquid environments. 316 stainless steel is preferred for corrosive chemicals or wastewater applications, while 304 stainless steel is commonly used in general industrial and food processing settings.

Yes, float balls can be tapped with virtually any thread specification, including 1/4-20, 3/8 NPT, 1/2 NPT, and 3/4 NPT, to match existing valve stems or fittings. Custom through tubes and hook attachments are also available to integrate seamlessly into double float valve assemblies.

Each float can be pressure tested using dedicated equipment to confirm it withstands the specific operating pressures of its intended system. This testing ensures reliable, leak-free performance in high-pressure vacuum tanks, steam traps, and industrial process control applications before shipment.

Double float valves are widely used in food processing, chemical manufacturing, wastewater treatment, and industrial process control, as well as in vacuum tank, sump pump, and steam trap systems. Their dual-stage design provides added reliability wherever precise liquid level monitoring and shutoff redundancy are required.

Yes, custom magnets can be sourced and assembled inside float balls to trigger reed switches or sensors at exact liquid levels. This magnetic integration is especially useful in double float valve systems requiring precise, repeatable activation points for control or alarm functions.
