  • Actuator for well-head valve or other similar applications and system incorporating same
    Patent number: 6953084
    Abstract: An electrical actuator is particularly suited for driving a wellhead valve for regulating the flow of natural gas from a production well. The electrical actuator can be driven using the existing local power supply in wellhead valve systems, typically a solar panel and a battery. The electrical actuator may include a gear reduction train, a brake and a manual input override with clutch protection. The electrical actuator can be configured in three different operational modes that provides a predetermined position upon power loss including fail-bias fixed, fail open and fail bias closed.
