Swagelok® Medium-Pressure Trunnion-Style Ball Valves (CTB Series)
Swagelok CTB series trunnion-style ball valves offer low-torque and quarter-turn operation in a compact design, providing positive shutoff in applications up to 20 000 psig (1378 bar).
Request CTB Series Valve InformationSwagelok® CTB series medium-pressure ball valves deliver reliable performance with cone and thread end connections. These trunnion-style ball valves feature an innovative direct-load design that seals consistently across a full range of pressures (up to 20 000 psig or 1378 bar), even if a system is depressurized and repressurized, enabling improved actuation of control systems. They also feature a stem seal design that maintains full pressure rating throughout the entire operating temperature range and a bottom-loaded stem design that eliminates stem blowout and enhances operator safety.
CTB series valves are available in two-way (bidirectional) or three-way (common-side or bottom-inlet port) configurations with flow coefficients ranging from 0.26 to 3.5. They also are available with an ISO 5211-compliant pneumatic actuator and materials selected in accordance with NACE MR0175/ISO 15156 for sour gas applications.
Two orifice sizes are available (6CTB, and 9CTB 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. Find the right valve size for your application with our flow coefficient calculator.
