Abstract
A method of controlling a valve can include monitoring electrical power supplied to the valve and/or monitoring pneumatic pressure supplied to the valve. Upon failure of the electrical power and/or pneumatic pressure, the operative position of the valve can be held in its last position and/or moved to a fail-safe position. Whether the valve position is held, or moved to a fail-safe position, can be independent of, or dependent upon, the position of the valve and/or an error in position of the valve.
