While reviewing an incoming order for a Ty … While reviewing an incoming order for a Type 9500 Butterfly Valve, it was discovered that two parts, namely the Thrust Plate and Thrust Plate Cap Screws, were not called out for Commercial Grade Dedication per Fisher Manufacturing Procedure (FMP) 2K27. These parts are considered an essential-to-function part in order for the valve to perform an active safety function.</br>Upon discovery of this possible failure to comply, an investigation was performed on all Safety-Related Type 9500 Butterfly Valves that have been shipped, are in active service or inventory, and are required contractually to be dedicated and it was determined that the Thrust Plate and Thrust Plate Cap Screws in these valves were supplied commercial grade and had not been dedicated per FMP 2K27.</br>The Thrust Plates retain the Thrust Sleeve Assemblies which provide a bearing surface for the Valve Shaft. The Thrust Sleeve Assemblies also provide adjustment to the Valve Body Liner. The Thrust Plate Cap Screws retain the Thrust Plates. Without the Thrust Plates or the Thrust Plate Cap Screws, there is a risk that the Thrust Sleeve Assemblies will disengage from the Valve Body, preventing the valve from performing its active safety-related function.</br>It is Fisher's opinion that while the Thrust plates and Thrust Plate Cap Screws were not dedicated, the failure to dedicate does not pose an inherent safety risk given the materials used. </br>Fisher will revise its procedures to ensure that this issue is corrected and does not happen in the future.</br>Action Required: Fisher will supply properly dedicated Thrust Plates and Thrust Plate Cap Screws for the affected valves that are in inventory or service, at no cost to the affected customers.</br>Notification has been made to plants with the Type 9500 Butterfly Valves for; Cooper Plant (NPPD), Vogtle Plant (Georgia Power), Ft. Calhoun Plant (OPPD), and Millstone Plant (Dominion) and specific valve order numbers and serial numbers were provided. numbers and serial numbers were provided. +
