Swagelok Co. has introduced a larger size of its FKB series medium-pressure ball valve. Designed for improved cycle life in the field, the trunnion-style ball valves provide a leak-tight seal for applications up to 15,000psig and features Swagelok’s patent-pending direct load design, which delivers a more consistent seal across a full range of pressures. The two-way 8FKB ball valve complements the original 6FKB ball valve introduced in May 2009. The 8FKB ball valve, with a 0.375in orifice, offers 1/2in gaugeable Swagelok® medium-pressure tube fitting end connections or 1/2in female NPT. The 6FKB ball valve is available with 0.209in orifice and 1/4, 3/8, or 1/2in. All valves feature 316 stainless steel body construction, and reinforced PEEK seat seals. The valves are rated for temperatures from 0 to 250F and maintain a full pressure rating throughout the entire operating temperature range. Multiple O-ring materials are available, including nitrile, fluoroelastomer, and perfluoroelastomer. Designed for the higher working pressures of the oil and gas industry, the Swagelok line of medium pressure products also includes medium pressure fittings and seamless tubing. The 316 stainless steel fittings are available in a variety of configurations for use with medium pressure stainless steel tubing, both heavy wall annealed and cold-drawn 1/8 hard, and SAF 2507™ super duplex tubing.
