BETTIS Type CBB 725-SR80
The Bettis Type CBB 725-SR80 is a heavy-duty spring-return pneumatic actuator engineered for reliable and precise quarter-turn valve automation. Designed to deliver consistent torque output and dependable fail-safe operation, this actuator is ideal for critical service applications in oil & gas, petrochemical, power generation, and industrial process systems.
With a robust ductile iron or carbon steel housing, the CBB 725-SR80 offers long-term durability in demanding environments. Its spring-return configuration ensures automatic fail-close or fail-open positioning upon loss of air supply. The actuator features a high-capacity power cylinder, precision-machined drive components, and adjustable travel stops for accurate end-of-stroke alignment. The design supports compatible mounting interfaces for a wide range of rotary valves.
