A. General Information
The importance of maintenance planning is the key to good
plant operation. Part of that planning involves making sure
that replacement parts needed to repair valves are available
at the jobsite when required. Developing and implementing
a standard valve maintenance plan will quickly pay for itself
by eliminating costly downtime, unscheduled outages, etc.
B. Inventory Planning
The basic objectives in formulating a replacement parts plan
are:
•
Prompt Availability
•
Minimum Downtime
•
Sensible Cost
•
Source Control
Having parts immediately available from plant storeroom
inventory is obviously the best way to accomplish those
objectives. Since it is impractical to have every part that
might be needed to accomplish a given repair in stock at
all times, guidelines for establishing meaningful inventory
levels are summarized in the Table 9.
C. Replacement Parts List
Consult the Recommended Spare Parts list (see Section
XXIII of this manual) to determine the parts to be included
in the inventory plan.
Select the desired parts and determine those required for
proper maintenance of the valve population in the plant.
D. Identification and Ordering
Essentials
When ordering service parts, please furnish the following
information to insure receiving the correct replacement
parts:
1. Identify valve by the following nameplate data:
a. Size
b. Type
c. Temperature Class
d. Serial Number
Example:
16” 13906/114-2
SIN TC-56788
2. Specify parts required by:
a. Part Name
b. Part Number (if known)
c. Quantity
XXI. Replacement Parts Planning
Each time replacement parts are needed, keep these points
in mind:
• BHGE designed the parts.
• BHGE guarantees the parts.
• Consolidated valve products have been in service since
1879.
• BHGE has worldwide service.
• BHGE has fast response availability for parts.

Note 1:
Predicted availability means that percentage of time the
user plant will have the right parts to make the proper
repair on the product, (i.e., if CLASS I parts are stocked
at the owners facility, the parts needed to repair valve
in question will be immediately available in 70% of all
instances).
