Floating Ball Valve

Single Piece Design

A floating ball valve is a type of quarter-turn valve used to stop or start the flow of liquids or gases through a pipeline. The ball in the valve is not fixed in place and floats slightly downstream to maintain contact with the seat under pressure.

A floating ball valve has a ball that floats between the seats under pressure, while a trunnion-mounted ball valve has additional mechanical support from trunnions or bearings to withstand higher pressures.

Yes, floating ball valves are versatile and can handle both on-off service and moderate throttling applications depending on the design and specifications.

Maintenance schedules depend on operating conditions, but regular inspection, lubrication, and replacement of seals or components as needed can prolong valve life and ensure optimal performance.
