A. Basic Guidelines

The following guidelines should be of assistance in developing a meaningful

replacement parts plan.
1. The total number of valves in service should be classified by size, type and

temperature class.

2. The parts inventory should be classified by the tendency to require

replacement.
a. Class I – Most frequently replaced
b. Class II – Less frequently replaced but critical in an emergency

3. Parts for the valve types covered by this manual are classified on Tables 23.

“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.

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 25, 26 and 27 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 Figures 96, 97 and 98):

1.  Size
2.  Type
3.  Pressure/Temperature Class Rating
4.   Serial Numbers from both main valve and pilot valve

Example:

Main Valve: 2910R-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.

Examples:

M0RK-70

006

PSGK - 31

XXIV. Replacement Parts Planning

Always use appropriate

restoration

procedures.

Do not interchange

parts from one valve

to another.
