Abstract

Embodiments of a method of operating a safety valve and a safety valve system are provided. The valve system includes a valve, an actuator, a mechanical override, and an indicator. The actuator includes a fail-safe mechanism and the indicator is configured to indicate whether the fail-safe mechanism is operable during use of at least one of the actuator and the mechanical override. In one embodiment, a method of operating the safety valve includes actuating the valve into an open position and sending a signal to indicate that the fail-safe mechanism is operable to move the valve to the closed position, while the valve is in the open position.
