Looking for a high-performance shut-off valve that’s simple, reliable, and cost-efficient? The Floating Ball Valve is the perfect solution for general-purpose fluid control. At Perfect Engineers, we manufacture precision-engineered floating ball valves that are trusted by industries across water, oil, gas, steam, chemicals, and utilities—offering tight sealing, low torque operation, and easy maintenance.
A Floating Ball Valve has a ball that is not anchored but held in place by two elastomeric seats. When fluid pressure is applied, the ball floats slightly downstream, pressing against the seat and creating a tight, leak-proof seal.
This design is widely used for low to medium pressure systems, typically in valves up to 6” in size.

No. Use V-Port ball valves for throttling. Floating valves are best for on/off service.
Yes—for low to medium-pressure steam, use graphite-seated floating ball valves.
Use metal-seated or cavity-filled floating valves for paints, slurries, or sticky fluids.
Yes. Available with cavity-filled, tri-clamp, and FDA-approved designs.
