Abstract
Methods and apparatus to indicate a position of a valve are described. An example position indicator apparatus includes a status indicator to provide an indication that corresponds to a displacement of a poppet relative to a seat ring of the fluid valve to determine one of a plurality of predetermined operational positions of the fluid valve. A follower is coupled to the poppet to follow movement of the poppet between the plurality of predetermined operational positions of the fluid valve. A coupler operatively couples the status indicator and the follower.
