In demanding industrial environments where reliability, precision, and safety are paramount, the Flange Floating Ball Valve from our factory has become a trusted solution for fluid control. Engineered to meet the rigorous standards of API 608, API 6D, BS 5351, and ASME B16.34, this valve is designed not just to perform—but to last.
One of the key design advantages of the flange floating ball valve is its lip-shaped sealing structure. This specialized seat provides excellent sealing performance, while also reducing the friction coefficient. As a result, operators benefit from lower torque requirements and smoother control, making the valve ideal for frequent operation and quick opening or closing. The compact structure and lightweight design further enhance its usability, especially in space-constrained installations.
Safety is central to the valve’s construction. The bottom-mounted valve stem prevents the stem from ejecting under pressure, a critical feature in high-stakes industrial settings. In the event of a fire or system failure, the design allows the stem to maintain a metal-to-metal seal with the valve body, ensuring continued containment and minimizing leakage risks. Additionally, the valve is equipped with both fireproof and anti-static features to further improve operational security.
Ease of use has also been carefully considered. The handle clearly indicates the valve’s open or closed position, and thanks to the flat-head stem design, the handle connection remains accurate without misalignment. Locking holes at both the fully open and fully closed positions help prevent accidental operation, which is especially important in complex pipeline systems where flow mismanagement could result in safety hazards or system disruption.
Our flange floating ball valve supports a wide range of material configurations, including carbon steel, stainless steel, duplex stainless steel, Monel, and aluminum bronze. Seat insert materials such as PTFE, RPTFE, Nylon, Devlon, and PEEK allow the valve to operate effectively across diverse media and temperature ranges—from -29°C to 200°C with soft seats, and up to 450°C with metal seats. With sizes ranging from 1/2" to 10" (DN15–DN250) and pressure ratings from Class 150 to Class 600 (PN10–PN64), this valve can be customized for everything from tap water and sewage systems to applications in petroleum, chemical processing, pharmaceuticals, power generation, and shipbuilding.
Whether operated manually by lever or gear, or automated with electric or pneumatic actuators, the flange floating ball valve from our factory is engineered for dependable performance, long service life, and minimal maintenance. It’s this combination of durability, safety, and ease of use that makes it a preferred choice for fluid control in industries where there is no room for compromise.
