Abstract
The disclosed embodiments include an apparatus and a method for controlling fluid flow. In accordance with certain of the disclosed embodiments, a valve is disclosed that comprises a yoke that encases a coil. The yoke has a gap adjacent to a central aperture of the yoke. A core tube is placed in the central aperture. The core tube has a core slidingly disposed within an interior chamber for controlling a fluid flow rate from a flow inlet to a flow outlet. A current is provided to the coil. Magnetic flux, generated by the coil in response to the current, is directed through the gap to cause the core to move proportionally based on the amount of current provided to the coil for changing the fluid flow rate from the flow inlet to the flow outlet.
