CBA-Series Scotch-Yoke Pneumatic Actuators
 |
Mechanical Components
The Bettis CBA-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 economical, low maintenance actuators provide a reliable means of automating your valve. Available with optional features and controls to meet your most demanding automation needs. The CBA-Series, available in double-acting and spring-return models, are independently certified to BS 5490: 1977- IP66 and IP67M for water ingress protection.
Operating Ranges
Double-acting CBA-Series actuators are available with guaranteed minimum torque outputs to 12,245 lb-in (1,384 Nm).
The CBA-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 CBA-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, special non-PED low temperature trim allows operation to -40°F (-40°C). Consult factory when temperature requirements exceed these limits.
Operating pressures for the CBA-Series range from 40 to 150 PSIG (3 to 10 BAR).
New Features for Demanding Applications
The new generation Bettis® CBA-Series actuators were specifically designed for those applications where water ingress protection and enhanced corrosion protectionwere paramount.
