CBA-300 Series pneumatic actuators are compact, lightweight and ideal for automating ball, butterfly, non-lubricated plug valves, or any quarter-turn rotating mechanism. Available in double-acting and spring-return models and certified to IP66 and IP67M.

CBA-Series Valve Actuators
CBA-Series pneumatic actuators are compact, lightweight, ideal for automating ball, butterfly, non-lubricated plug valves, or any quarter-turn rotating mechanism. Avail in double-acting and spring-return models. Certified to BS5490: 1977-IP66 and IP67M.

CBB-Series Valve Actuators
CBB-Series pneumatic actuators are compact, lightweight, ideal for automating ball, butterfly, non-lubricated plug valves, or any quarter-turn rotating mechanism. Avail in double-acting and spring-return models. Certified to BS5490: 1977-IP66 and IP67M.

D-Series Valve Actuators
D-Series reliable pneumatic rack and pinion actuators. Designed for operation of plug, butterfly, ball valves, and other 90o turn devices. They are compact and lightweight, making them suitable for installation within areas of tight piping connections.

E-Series (Pneumatic & Hydraulic Scotch-Yoke)
E-Series pneumatic and hydraulic scotch yoke actuators operate ball, butterfly, plug valves, and other 90 degree turn devices. They provide a reliable method for operating valves via remote or automatic control by incorporating a variety of accessories.

Gas/Hydraulic Valve Actuators
Bettis Gas/Hydraulic actuators use high pressure pipeline gas supply as their power source in gas/transmission pipelines. Available in rotary and linear versions and can be supplied with remote control and linebreak systems.

G-Series Valve Actuators
The G-Series scotch yoke pneumatic and hydraulic actuator has state-of-the-art features and an enhanced modular design for improved efficiency, reduced wear and extended life. Available with symmetric or canted yoke. SIL 3 suitable and ATEX certified.

GVO-Linear Valve Actuators
GVO-Series pneumatic linear actuators offer safety shutdown and control applications. Available for low or high pressure operation in double-acting, spring-return or fail-safe configurations. Also available with optional jackscrew manual overrides.

HD-Series Valve Actuators
The HD-Series actuators provide a practical and reliable method for opening and closing valves by remote control without the need for expensive and unnecessary gearing, hydraulic pumps or other motor driven devices.

PressureGuard Valve Actuators
The PressureGuard Self-Contained Hydraulic Emergency Shutdown Systems are designed to provide valve shutdown when external power source is not available or dependable. Used with rotary or linear spring-return hydraulic operators for a fail-safe system.

TorqPlus Series Valve Actuators
TorqPlus electric actuators employ a unique modular design to allow for simple retrofits/upgrades using over 200 different accessory kits. All components can be added inside NEMA 4 or NEMA 4/7 rated housings. Torque range from 100 in/lb to 20,000 in/lb.
