XXIV. Replacement Parts Planning (Cont.)
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 BHGE Green Tag
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 - 7)
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 61, 62 and 63.
