A floating ball valve is a quarter-turn valve where the ball is supported by seats rather than fixed trunnions. It is usually for low to medium-pressure systems requiring reliable shutoff, compact design, and cost efficiency.
Pressure-Driven Sealing
Line pressure automatically pushes the ball against the downstream seat, increasing sealing force as pressure rises.
Self-Adjusting Seat Contact
The floating ball can slightly move to align with the seat, ensuring consistent sealing and reducing leakage risk.
Suitable for Medium and Low Pressure
Performs most efficiently in Class 150–300 systems where trunnion support is unnecessary.
Lower Structural Cost
No trunnion design reduces material and manufacturing costs.
Water Supply Systems
Pipeline shutoff in municipal water and building distribution systems
Oil & Gas Utilities
Low to medium pressure pipelines for oil, gas, and fuel transfer
Chemical Processing (Non-abrasive Media)
Control of general chemicals with proper material selection
HVAC & Building Systems
Flow control in heating, cooling, and utility pipelines
