Zusammenfassung:A check valve assembly including a position indicator and method of operation, wherein the position indicator indicates the position of at least one of a plurality of flappers. The valve assembly including at least one bridge conductor and at least one pair of spaced apart mating conductors formed on at least one of a fluid flow opening and/or on a flapper stop. During operation, the bridge conductor bridges the pairs of conductors formed about at least one fluid flow opening thereby generating a signal to alert a controller that the flapper is in a closed position. Alternatively, or in addition to, the bridge conductor bridges the pair of conductors on the flapper stop thereby generating a signal to alert a controller that the flapper is in a full-open position.
