CBB-Series pneumatic actuators are compact, lightweight and ideally suited for automating ball, butterfly and non-lubricated plug valves, or any quarter- turn (90 degree) rotating mechanism. These efficient, low maintenance actuators, with optional controls, provide a reliable method of operating and confirming valve position for a fully automated process. The CBB-Series, available in double-acting and spring-return models, are independently certified to BS 5490: 1977 - IP66 and IP67M for water ingress protection.
Double-acting CBB-Series actuators, requiring pressure to rotate in either direction, are available with guaranteed minimum torque outputs to 12,245 lb-in (1,384 Nm).
The CBB-Series spring-return models require pressure in only one direction of travel and are suitable for fail clockwise or counterclockwise applications without modification. These models produce guaranteed spring ending torques to 4,971 lb-in (562 Nm).
Standard construction CBB-Series actuators are designed for operating temperatures of -20°F to +200°F (-30°C to +95°C). High temperature trim allows continuous operation from 0°F to +350°F (-18°C to +177°C). Additionally, low temperature trim allows operation from -40°F to +150°F (-40°C to +66°C). Consult factory when temperature requirements exceed these limits. Operating pressures for the CBA-Series range from 40 up to 150 Psig (3 to 10 Barg).
