Bettis Gas Hydraulic Linear Valve Operator

The Bettis™ Gas-Hydraulic Linear Valve Operator, engineered by Emerson, is a high-performance actuator system designed to provide precise linear motion for valves in remote, unmanned, or safety-critical applications. Utilizing pipeline gas as its power source, this operator converts pneumatic energy into controlled hydraulic force, enabling smooth, reliable, and fail-safe valve operation even under extreme pressure and temperature conditions. Built with robust gas-over-hydraulic technology, the Bettis Gas-Hydraulic Linear Operator ensures accurate valve positioning, consistent thrust output, and superior control performance. Its compact and corrosion-resistant construction makes it ideal for use in onshore and offshore oil and gas pipelines, wellhead systems, and emergency shutdown (ESD) applications. Designed for efficiency, safety, and long-term reliability, the Bettis Gas-Hydraulic Linear Operator integrates seamlessly with ESD systems, remote control setups, and line break detection systems, offering dependable operation when it matters most.
