LMFBR Large Valve Development. Comparison Study of Advantages and Disadvantages of Foreign Design of Offset Pivot Butterfly Valves with AMCO'S Offset Pivot Ball Valve

摘要

The purpose of this effort was to compare the advantages and disadvantages of foreign designs of offset pivot butterfly valves presented during a specialists meeting on Operating Experience and Design Criteria of Sodium Valves with the characteristics of the present AMCO offset pivot ball valve design concept. In addition, the comparison was directed to indicating if work on a butterfly concept should be initiated by AMCO. This work could be in parallel with or in lieu of, the present AMCO effort on an offset pivot ball valve for isolation valve purposes.
