Bettis™, CBA-300 Series pneumatic actuators combine the strengths of the new G-Series actuators while incorporating several new design economies for efficient and cost effective valve automation. The CBA-300 Series have enhanced water ingress and corrosion protection, are compact, lightweight and ideally suited for automating ball, butterfly and non-lubricated plug valves, or any quarter- turn (90 degree) rotating mechanism.
Double-acting CBA 300-Series actuators, requiring pressure to rotate in either direction, are available with guaranteed minimum torque outputs from 7,388 to 22,055 lb-in (835 to 2,492 Nm).
The CBA-300 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 from 2,532 to 10,457 lb-in (286 to 1,182 Nm).
Standard construction CBA-300 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 300-Series range from 40 up to 150 Psig (3 to 10 Barg).
