- 10CFR PART 21 REPORT - DEFECTIVE CAPACITY CONTROL VALVES -

SEVERAL CAPACITY CONTROL VALVES PURCHASED BY TRENTEC, INC, CINCINNATI, OHIO, FROM YORK INTERNATIONAL CORPORATION, YORK, PENNSYLVANIA, AS COMMERCIAL GRADE ITEMS AND DEDICATED FOR SAFETY-RELATED USE BY FARWELL

& HENDRICKS, INC (PRIOR TO BEING ACQUIRED BY TRENTEC, INC) WERE SUBSEQUENTLY FOUND TO CONTAIN A MANUFACTURING DEFECT. THE MANUFACTURING DEFECT IS DUE TO IMPROPER MACHINING (LOCATION) OF HOLES IN THESE VALVES.

THE YORK INTERNATIONAL PART NUMBERS FOR THIS VALVE ARE #364-21538-000 (WHEN PURCHASED AS A SINGLE ITEM) AND #064-20838C (WHEN PURCHASED AS A SUBCOMPONENT OF A COMPRESSOR).

VALVES OF THIS TYPE WERE SUPPLIED AS SAFETY-RELATED VALVES TO BALTIMORE GAS & ELECTRIC (BG&E) COMPANY (CALVERT CLIFFS).

TRENTEC PERSONNEL HAVE BEEN IN CONTACT WITH BG&E PERSONNEL REGARDING THIS CONDITION AND HAVE REQUESTED THAT THESE POTENTIALLY DEFECTIVE VALVES BE RETURNED TO TRENTEC SO THAT ANY IMPROPERLY MACHINED PARTS COULD BE REPLACED.

AT THE PRESENT TIME, TRENTEC HAS NO INDICATION THAT ANY OF THE DEFECTIVE VALVES HAVE BEEN INSTALLED IN SAFETY-RELATED SYSTEMS. HOWEVER, TRENTEC PLANS TO OBTAIN FURTHER INFORMATION FROM BG&E IN THE IMMEDIATE FUTURE TO CONFIRM THE STATUS OF THE SUPPLIED VALVES.
