Floating Ball Valve

A floating ball valve is a highly versatile, quarter-turn rotary valve where the spherical ball is suspended in the flowing media rather than being anchored by a lower trunnion shaft. Utilizing standard thermoplastic or PTFE seats to cradle the ball, this design allows the ball to shift slightly downstream under line pressure, pushing it firmly against the downstream seat to create a highly effective, bi-directional seal. Operating via a stem that rotates the ball 90 degrees to rapidly open or close the flow path, these valves are prized for their lightweight, economical, and compact construction. They are an industry standard for standard-pressure applications across the oil, gas, water, and petrochemical sectors. As a leading platform of China ball valve manufacturers, we connect you with certified suppliers who precision-machine floating ball valves to ensure optimal stem-to-ball alignment—delivering reliable, leak-free isolation and effortless low-torque manual or automated actuation for global piping networks.
