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.

Abstract: An apparatus and method for manual operation of an actuator is disclosed. A mechanical override includes a housing coupled to the actuator, a drive ring, and a shaft extending through a bore of the housing. The drive ring rotationally keys to the bore such that the drive ring is capable of axial movement within the bore in response to automatic operation of the actuator. A backstop limits axial movement of the drive ring during manual operation. A thread located on an external portion of the shaft threads to the drive ring. In the manual operation, the shaft rotates through the drive ring imparting axial movement to the shaft capable of moving a valve between a first position and a second position. The override provides visual indication of the valve position during both automatic and manual operation. The backstop may be an insert that selectively permits movement of the shaft to a failsafe position in response to a temperature or pressure change.

Abstract: A dual piston valve actuator operable to provide an initial thrust force that is greater than a subsequent thrust force for moving a gate valve from a closed position to an open position. The actuator may include a first piston and a second piston movably disposed within a bore of the first piston. The first piston may define a first piston area for proving the initial thrust force, and the second piston may define a second piston area (that is less than the first piston area) for providing the subsequent thrust force. Movement of the first piston is limited relative to the second piston for moving the gate valve using the initial thrust force an initial portion of the valve stroke, while moving the gate valve using the subsequent thrust force the remaining portion of the valve stroke.

In one embodiment, the pressure control system may include a housing defining an upper chamber and a lower chamber, and a piston disposed between the upper and lower chambers. A valve may be coupled to the piston that is operable to control fluid communication between the upper chamber and the lower chamber.

Abstract: An apparatus and method for manual operation of an actuator is disclosed. A mechanical override includes a housing coupled to the actuator, a drive ring, and a shaft extending through a bore of the housing. The drive ring rotationally keys to the bore such that the drive ring is capable of axial movement within the bore in response to automatic operation of the actuator. A backstop limits axial movement of the drive ring during manual operation. A thread located on an external portion of the shaft threads to the drive ring. In the manual operation, the shaft rotates through the drive ring imparting axial movement to the shaft capable of moving a valve between a first position and a second position. The override provides visual indication of the valve position during both automatic and manual operation. The backstop may be an insert that selectively permits movement of the shaft to a failsafe position in response to a temperature or pressure change.
