When is part substitution okay
- Fisher Controls International, Inc., Marshalltown, IA (United States)
Will nonoriginal equipment manufacturers (non-OEM) replacement parts allow control valves to operate in their original design parameters This is a concern for maintenance and process engineering groups. New regulations on emissions and plant safety put more emphasis on the integrity of the control equipment. Now maintaining the control valve's performance is more important than ever before. As in all things, control valves do wear from continuous operations and must be repaired or serviced. A critical issue must be deliberated on which replacement program should be used, replacement in kind or will fit parts. However, the decision is not solely based on replacement part costs. Now, replacement parts must meet the definitions set by OSHA 1910.119 for process safety. Replacement in kind means a replacement that satisfies the design specifications. The key point is when and where can you use non-OEM parts and retain the valve's mechanical integrity and preserve your OSHA documentation. This paper discusses OSHA's governing rule; the control valve's effect on process safety management; impact of non-OEM parts; and recommendations.
