Abstract
A wellhead valve control system includes a removable actuator adapted to couple to a valve, the valve being operable via a first operational mode. The system also includes an actuator element associated with the removable actuator, the actuator element operable to modify the first operational mode of the valve to a second operational mode, the second operational mode being different from the first operational mode. The system further includes a control panel, positioned remotely from the valve, the control panel configured to control the actuator element to adjust a valve position in the second operational mode.
