An example apparatus in accordance with the teachings of this disclosure includes a valve body, a valve stem and a fluid flow control apparatus coupled to the valve stem. The fluid flow control apparatus is longitudinally displaceable between a first position and a second position to control fluid flow through a flow aperture of the valve body. The apparatus also includes a valve position indicator including an identifier device coupled to the valve stem. In the first position, the wireless identifier device associated with a first value indicative of the first position of the fluid flow control apparatus.
