Abstract
An automatic control valve is provided for generating power based on fluid flow. In one example, the automatic control valve includes a primary passage including a valve seat disposed between an inlet and an outlet and a valve seat. A valve member is moveable between an open position and a closed position depending on the fluid flow. The automatic control valve includes a rotatable valve stem that is affixed at one end to an impeller and operably affixed to a drive shaft of a generator at the other end. As fluid flows to move the valve member to an open position, the impeller with the rotatable shaft and the drive shaft of the generator rotate to produce electric power.
