Swagelok® Medium-Pressure Trunnion-Style Ball Valves (FKB Series)
Swagelok FKB series medium-pressure ball valves provide positive shutoff in applications up to 20 000 psig (1378 bar) and features an advanced design that reduces seal wear, improving reliability.
Request FKB Series Valve InformationThe advanced design of the Swagelok FKB series ball valve reduces seal wear and improves the reliability of connections across a full range of operating pressures (up to 20 000 pisg or 1378 bar) and temperatures. The trunnion-style ball features an innovative direct-load design to enable leak-tight performance and a bottom-loaded stem design to eliminate stem blowout, protecting operators.
FKB series valves are available with female NPT end connections and gaugeable Swagelok medium-pressure tube fitting end connections that reduce valve installation time and cost while providing robust tube grip and vibration resistance. CTB series valves are also available in two-way (bidirectional) or three-way (common-side or bottom-inlet port) configurations with flow coefficients ranging from 0.44 to 11.3. They can be configured with an ISO 5211-compliant pneumatic actuator and for “low emissions” certification per API 641.
Three orifice sizes are available (6FKB, 8FKB, and 12FKB series) and end connection sizes range from 1/4 in. to 1 in. Mounting options include panel mounting using an optional panel nut, two bolts through a panel into the top of the valve body, or bolting through body mounting holes with dual bolt patterns for OEM valve replacement.
