"A valve plug originally supplied as a spare parts order was returned to Fisher after the customer discovered a machining error was present on the plug. The Type 461 valve plug has a groove machined across the seating surface of the plug. This groove is required to provide a controlled leak rate thru the valve when the plug is on the seat. The issue recently identified shows that the machined groove did not extend through the full length of the seat. This could lead to a situation in which the intended/required leakage for this design is not fully achieved."

Affected plants are: Waterford-3 and St Lucie.

Mar.20. 2015 1:13PM No, 0375 P. 4 Fisher Information Notice: FIN 2015-01 Applicability:

This notice applies only to the subject equipment supplied by Fisher as identified above.

Discussion:

A valve plug originally supplied as a spare parts order was returned to Fisher after the customer discovered a machining error was present on the plug. The Type 461 valve plug has a groove machined across the seating surface of the plug. This groove is required to provide a controlled leak rate thru the valve when the plug is on the seat.

The issue recently identified shows that the machined groove did not extend through the full length of the seat. This could lead to a situation in which the intended I required leakage for this design is not fully achieved.

Action Required: Evaluate any affected Type 461 valve plugs in inventory to ensure the machined groove extends across the plug seating area.
