XXIV. Replacement Parts Planning
A. Basic Guidelines
The following guidelines should be of assistance in developing a meaningful replacement parts
plan.
A.
The total number of valves in service should be classified by size, type and temperature
class.
B.
The parts inventory should be classified by the tendency to require replacement.
Class I – Most frequently replaced
Class II – Less frequently replaced but critical in an emergency
C.
Parts for the valve types covered by this manual are classified on Tables 20. "Qty. parts" is
the number of parts or sets which is recommended to achieve a desired need-probability, as
it relates to the total number of valves in service by size and type. For example, a "Qty. parts"
of 1 for "Valves in service" of 5 means that 1 part should be stocked for each 5 valves of the
same type and size in service.
D.
When ordering replacement parts, please specify in accordance with applicable
nomenclature (see Figures 1 to 7). Be sure to state the size, type and serial number of the
valve for which parts are required. When ordering pilot parts please state specific pilot type
(39PV07, 37 etc.)
For ease of maintenance O-Ring kits are available for each main valve and pilot type. A stock of
these kits should be kept on hand for maximum operating efficiency. See Tables 23, 24 and 25 in
Section XXVI.
B. Identification and Ordering Essentials
Identification and Ordering Essentials When ordering service parts, please furnish the following
information to ensure receiving the correct replacement parts.
Identify valve by the following nameplate data (Refer to Figures 61, 62 and 63):
A. Size
B. Type
C. Pressure/Temperature Class Rating
D. Serial Numbers from both main valve and pilot valve
Example:
Main Valve: 2910-40R-00-1-CC-MS-B-RF-GS-RS, TL12345-M
Pilot Valve: 39PV07-2-CC-B-GS-60, TL12346-P
How to verify Materials of O-Rings and Seals:
Kit coding indicates O-Ring and seals material.
