Float Valves for Automatic Liquid Level Control

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. Custom fittings, through tubes, and hooks can also be added to match your exact measurement device or valve system requirements.

Absolutely. Stainless steel float balls — particularly those in 304ss and 316ss — are ideal for food processing environments. They provide precise liquid level monitoring in tanks and vats containing oils, syrups, and other food-grade liquids, and their smooth finishes make them easy to clean and maintain.

Magnet integration involves custom-sourced magnets assembled inside the float ball to enable precise liquid level detection in systems using magnetic sensors or reed switches. This is particularly useful in vacuum tanks, sump pump systems, and automated process control applications where contactless level sensing is required.

Float balls are available in round shapes ranging from 1-1/2" to 14" diameter, and oblong shapes from 2x6" up to 7x16" and 9x14". Both shapes can be configured with custom threads, through tubes, and magnet integration. Custom sizes beyond standard inventory can also be added to meet specific application requirements.

Three finishes are available: Matte (unfinished with a visible weld ring), Brushed (polished smooth weld seam), and Fully Polished (mirror finish). The choice of finish depends on your application environment — polished finishes are preferred for food-grade and hygienic systems, while matte is suitable for general industrial use.

Yes, we ship directly to customers worldwide. With a large inventory of common sizes ready to ship, lead times are kept to a minimum. Custom configurations may require additional time depending on specifications. Contact us directly at (416) 805-8132 or richard@castingtechnologies.com for estimated delivery timelines for your order.
