Bettis-GH Series Gas Hydraulic Valve Operator
The Bettis™ GH-Series Gas-Hydraulic Valve Operator by Emerson delivers reliable, high-torque rotary motion using gas-over-hydraulic power, ideal for remote pipeline and wellhead valve automation.
The Bettis™ GH-Series Gas-Hydraulic Valve Operator, engineered by Emerson, is a high-performance gas-over-hydraulic actuator designed to deliver reliable rotary motion for quarter-turn valves used in remote pipeline and wellhead operations. Utilizing pipeline gas as the power source, the GH-Series actuator converts pneumatic energy into hydraulic force, providing smooth, powerful, and controlled valve movement—even under extreme pressure and temperature conditions.
Built on proven Scotch yoke technology, the Bettis GH-Series combines robust mechanical design with hydraulic precision, ensuring accurate valve positioning, consistent torque output, and fail-safe operation during power loss or system failure. Its modular and field-serviceable construction allows for easy maintenance and integration with emergency shutdown (ESD), remote control, and line break detection systems.
Designed for onshore and offshore pipelines, gas storage, and production facilities, the Bettis GH-Series actuator provides exceptional reliability, low maintenance costs, and long service life—making it a trusted solution for critical flow control applications in the oil and gas industry.
