NONCOMPLIANCE SITUATION AND BRIEF HISTORY

On Tuesday April 25, 2000, the customer was performing receiving inspection and noticed that the set pressure information on the Code Plates and the Name Plates do not conform to the specification requirements or the history docket testing information. The customer called the Quality Assurance Department of Dresser Valve Division to discuss the finding. It appears that the set pressure information on the plates has been interchanged.
