| Title | Part 21 Notification - Solenoid Valve May Not Perform Its Function |
| Event Description | On July 13, 2009 Flowserve US Inc. Raleigh, NC was notified by Exelon - Byron Nuclear Power Station that they identified a potential problem with a Borg-Warner (BW/IP) Solenoid Valve (BW/IP Part No. 86868) received by Exelon as it was being tested by their Electrical Maintenance Technician. Flowserve conducted an evaluation of the issue.
Flowserve's evaluation discovered that there existed dimensional deviations on the valve body parts that may cause the Solenoid Valve not to perform its intended function. Flowserve inventory discovered that the dimensional deviation also existed on 8 body parts in the current inventory and it was determined that this part was produced by the same subcontracted machining supplier since 2004. This renders the Solenoid Valve Body parts suspect from that time. This Solenoid Valve Body part is used in Solenoid Valve assembly models identified by the following Borg-Warner / Flowserve Part numbers: 86868 - Solenoid Valve Assembly - Normally Open; 86868-1 - Solenoid Valve Assembly - Normally Closed; 90628 - Solenoid Valve Assembly - Normally Open; 90638-1 - Solenoid Valve Assembly - Normally Closed.
