Bettis CBB Pneumatic Scotch Yoke Valve Actuator
CBB-Series are compact, lightweight, efficient, low-maintenance actuators that offer optional controls and provide a reliable method of operating and confirming valve position for a fully automated process. With its separate weather and pressure seal design, the actuator has dual redundancy.
Standard construction CBB-Series actuators are designed for operating temperatures of -30°C to +95°C (-20°F to +200°F). High temperature trim allows continuous operation from -18°C to +177°C (0°F to +350°F). Additionally, low temperature trim allows operation from -40°C to +66°C (-40°F to +150°F). Consult factory when temperature requirements exceed these limits.
Operating pressures for the CBA-Series range from 3 to 10 barg (40 up to 150 psig).
