XXIV. Replacement Parts Planning (Cont.)
XXV. Genuine Consolidated Parts
The next time replacement parts are needed, keep these points in mind:
• Baker Hughes designed the parts
• Baker Hughes guarantees the parts
• Consolidated valve products have been in use since 1879
•
Baker Hughes has worldwide service
• Baker Hughes has fast response availability for parts
C. Positive Identification of
Main Valve and Pilot Valve
Combinations
POSRV’s shipped direct from the factory to the
end-user probably have main valves and pilot valves
with identical serial numbers (S/N’s). Those shipped
unconnected to the Baker Hughes Green Tag Center
(GTC) network may have main valves and pilot
valves with different S/N’s. During service and repair,
the following inspection steps will ensure the proper
match of main valves to pilot valves.
1. Record main valve and pilot valve S/N’s of
original POSRV’s in plant records.
2.
Inspect S/N’s for agreement with Step 1, after
any disassembly involving removal of pilot valve
from main valve.
3. Make sure the set pressures of the main valve
and pilot valve are identical.
4. Check O-Ring and Seals Kit material code
to ensure they are the same for main valve
and pilot valve. Any discrepancies should be
promptly report to the appropriate plant authority.
Specify parts required by:
1. Part Name (See Nomenclature, Figures 1-9)
2.
Part Number (if known)
3. Quantity
In addition, the main valve serial number is stamped
on the top edge of the outlet flange. Be sure to
include the one or two letters preceding the figures
in the serial number. Typical valve nameplates are
shown in Figures 96, 97 and 98.
