Swagelok 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 pisg 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.
