METC Test Valve No. F-4 was an 8-inch segmented ball or visor valve design developed and manufactured by Fairchild Controls System under contract to the Department of Energy. The valve completed slurry testing, accumulating a total of 3191 valve cycles of which 2625 cycles were with material transfer. However, several internal leak rate measurements exceeded the METC failure criteria. Post test inspection revealed damage to the seats. Results of testing showed that internal leakage increased as test pressure increased and was affected by cycling pressure. A cycling pressure of 800 psig resulted in a higher internal leakage than a 1600 psig cycling pressure. In addition, the variability associated with measuring internal leakage also increased as test pressure increased. 5 refs., 10 figs., 1 tab.
