Overview
ASME Class 150/300 valves with Stellite® seats for durability in high-temperature operation
Durable Full Port Flanged Ball Valve with Exceptional Corrosion Resistance
The F15/F30 Series flanged floating ball valves are investment cast, ASME B16.34 Class 150 and Class 300 full-port ball valves. They offer a variety of optional trims and configurations, including soft-seated, metal-seated, and V-ball control valve trims, and are widely used across global industries. The F15/F30 Series ball valves deliver exceptional value and reliable operation in a rugged flanged ball valve design suitable for a wide range of service conditions. The F15/F30 Series flanged ball valve design ensures bubble-tight shutoff and low operating torque. Sizes ½” - 2” feature Bray’s Smart Stem™ technology for internally continuously pre-loaded packing. Sizes 2½” - 12” feature an independent packing gland that can be easily adjusted without removing mounting hardware or the actuator. The packing gland features a special profile designed to distribute load evenly across the packing. The dynamic load packing is self-adjusting via Belleville springs, compensating for environmental changes and wear, ensuring maintenance-free operation and extended service life. Larger F15/F30 flanged ball valves feature bearing-supported ball construction to reduce operating torque. The metal-seated F15/F30 flanged ball valves feature Stellite® cobalt-chromium alloy seat overlay, providing excellent corrosion resistance, higher operating temperatures, and superior wear resistance with high hardness. Metal-seated F15/F30 flanged ball valves feature butt-seal shutoff meeting or exceeding CI 70-2 Class V, with optional Class VI shutoff available. F15/F30 Series flanged ball valves are available in stainless steel (CF8M), carbon steel (WCB), and special alloys (such as Alloy 20, Hastelloy, etc.), with other dissimilar alloys available on request. Non-fire-safe versions feature standard stem packing. API 607 fire-safe trims feature graphite stem packing. F15/F30 Series valves feature an integrally cast ISO 5211 mounting pad for easy automation. * * Not available on all sizes. Refer to product manual for details.
