Text version of the page

www.swagelok.com Medium-Pressure Ball Valves FKB Series Swagelok FKB series trunnion-style ball valves offer lowtorque, quarter-turn operation in a compact design providing positive shutoff in applications up to 15 000 psig (1034 bar). Other features include: �¡ Flow coefficients (Cv) from 0.44 to 11.3 �¡ Gaugeable Swagelok medium-pressure tube fitting and female NPT end connections �¡ 2-way (on-off) and 3-way (switching) flow patterns �¡ Nitrogen seat tested and shell tested to ensure product integrity �¡ Positionable bar handle and ISO 5211-compliant pneumatic actuators �¡ Manual valve panel and shoulder mounting are available as options. Pressure-Temperature Ratings Temperature °F (°C) O-Ring Material Fluorocarbon FKM HNBR Perfluorocarbon FFKM Working Pressure, psig (bar) 0 (–17) to 250 (121) 20 (–6) to 185 (85) 15 000 (1034) — 15 000 (1034) — — 15 000 (1034) For more information about pressure ratings of valves with medium-pressure tube fitting end connections, see the Swagelok Medium-Pressure Gaugeable Tube Fittings and Adapter Fittings catalog, MS-02-335. Important Information About Swagelok Ball Valves ð® Swagelok ball valves are designed to be used in a fully open or fully closed position. ð® Valves that have not been cycled for a period of time may have a higher initial actuation torque. Swagelok® mediumpressure tube fitting end connections: �¡ reduce valve installation time and cost �¡ provide robust tube grip and vibration resistance. Trunnion-style ball with innovative direct-load design (patent-pending): �¡ seals consistently across a full range of pressures, even if system is depressurized and repressurized �¡ ensures reliable operation for improved actuation of control systems. Positionable handle with unique stop disk: �¡ provides flexibility in component layout, enabling reduced system footprint. Bottom-loaded stem design: �¡ eliminates stem blowout and enhances operator safety. Innovative stem and end connection seal design (patent-pending): �¡ maintains full pressure rating throughout the entire operating temperature range �¡ reduces seal wear that can lead to shell leakage.
