BAC FB is a flanged, full-bore floating ball valve for process isolation in chemical, petrochemical, gas, LPG and oil & gas applications. It is suited to installations where reliable shut-off, controlled fugitive emissions and robust mechanical construction are important for process continuity and plant safety. AxFlow can support selection against the required pressure class, nominal size, materials and operating conditions.
The valve uses a split-body construction with a floating ball, relief seats, an anti-static device, a pressure-balance hole in the ball and a blow-out-proof stem. A self-adjusting double stuffing box supports stem sealing and maintenance control. BAC specifies fugitive-emission performance according to ISO 15848 Class BH and wetted internal parts in accordance with ANSI/NACE MR0175/ISO 15156.
The FB range is available in Class 150-300 from 1/2 to 8 inches and in PN16-40 from DN15 to DN200. The standard range is designed to ISO 17292 / EN 1983, with ASME B16.5 RF or EN 1092-1 flanges, ISO 5211 top flanges and fire-safe testing to EN ISO 10497 / API 607. BAC also lists options including API 6D, an emissions-control port and selected internal coatings.
For maintenance and lifecycle planning, the standardized face-to-face dimensions, actuator interface and documented material options help engineers match the valve to an existing piping and automation concept. The double stuffing box and blow-out-proof stem address common leakage and service concerns around the stem area. Correct selection of materials, pressure class and options can reduce avoidable maintenance interventions and support dependable shut-off over the valve lifecycle.
