Bettis G-Series Hydraulic Valve Actuator

The Bettis™ G-Series Hydraulic Valve Actuator, engineered by Emerson, is a rugged and reliable scotch yoke actuator designed to provide high-performance hydraulic operation for quarter-turn valves used in the oil and gas, petrochemical, marine, and power industries. Built for precise torque control and dependable valve automation, the G-Series actuator utilizes the proven scotch yoke mechanism, which efficiently converts linear piston motion into rotary output. This design delivers high torque at both ends of the stroke, making it ideal for ball, butterfly, and plug valves that require smooth, controlled movement under high-pressure conditions. The hydraulic-powered G-Series actuator ensures reliable operation even in remote or hazardous environments where electric or pneumatic power may be unsuitable. With its robust construction, corrosion-resistant materials, and modular design, it offers long-term performance with minimal maintenance
