Description

For more than 40 years, Bettis™ has combined its ingenuity with high quality standards, continuously pioneering valve actuator technology. Beginning with the Robotarm scotch-yoke concept, Bettis, innovations have become today's standards for valve control in virtually every part of the world. The company operates in accordance with ISO 9001 and BS-5750 certifications and maintains a formal Total Quality Management program to assure product excellence. Continuing our innovative tradition, Bettis introduces the latest valve automation advancementthe G-Series Robotarm II™ quarter-turn actuator.

In developing the G-Series actuators, Bettis improved a basic concept - the Reaction Bar, by adding our new state-of-the-art Powr-Swivl™, replaceable bearings, highly efficient wear and corrosion resistant coating system, and tension rod compressed spring. This enhanced design greatly improves efficiency, reduces wear and extends the actuator's life. The combining of these technologies, enhancements, and superior quality control techniques produced an assembly which became the heart of our new extended service actuators - the G-Series.
