Fire-safe designs meet API 607 standards for high-temperature safety compliance
Series F15/F30 Flanged Floating Ball Valves are investment cast, ASME B16.34 Class 150 & 300 full port valves designed for reliable performance across various industries. They offer exceptional value and dependable operation in a durable flanged design, with optional trims including V-ball control valve configurations.
Engineered for bubble-tight shutoff and low operating torque, ½”–2” sizes use Bray’s Smart Stem™ with integral live-load packing, while 2½”–12” sizes feature an independent, easily adjustable packing gland with Belleville washers for self-adjusting compression. Larger sizes include a trunnion-type ball support to further reduce torque.
Resilient seated designs provide positive preloading for bi-directional, bubble-tight sealing under low pressure or vacuum conditions.
F15/F30 valves are available in stainless steel (CF8M), carbon steel (WCB), and specialty alloys such as Alloy 20 and Hastelloy. Non-fire safe versions use standard stem seals, while API 607 fire-safe trims use graphite stem seals. The valves also support easy automation with an integral-cast ISO 5211 mounting pad.
