Positive Identification Of Main Valve And Pilot Valve Combinations; Genuine Consolidated Parts - Baker Hughes Consolidated 4900 Series Instruction Manual

XXIII. 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 Consolidated 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 reported to
the appropriate plant authority.
Specify parts required by:
1. Part Name (See Section IX, Figures 1, 2, 3, 4 , 5,
6, 7 and 8)
2. Part Number (if known)
3. Quantity
Contact your local Green Tag Center (GTC).
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 46, 47 and 48.
