IX. PARTS ORDERING INFORMATION
There are three methods to obtain parts ordering information/numbers. These methods are listed below, in order
of ease of entering. The least expensive method is to utilize parts in kits where possible.
METHOD A - USE OF PRODUCT CODE.
Step 1. If available, obtain the 18 character product code
number from:
a. The Bill of Materials (BOM) sheet attached
here in.
b. The metal tag attached to the regulator.
NOTE: Some regulators may not have the prod-
uct code lo cated on the metal tag.
Step 2. Identify which kits or parts are desired from the
fol low ing:
a. The BOM, or refer to the cross-sectional draw-
ings.
b. Standard maintenance parts for a basic regu-
la tor are identifi ed on the BOM. Kit “A” con tains
seal(s), diaphragm(s) and gasket(s). Kit “B”
contains trim re place ment parts plus seal(s),
diaphragm(s) and gasket(s).
Step 3. Contact your local KM Sales Rep re sen ta tive and
specify the product code number along with a
description of any parts not included in the kits.
Costs of re quired parts (and kits) can be given by
the Sales Rep re sen ta tive.
METHOD B - NO PRODUCT CODE AVAILABLE
- DISASSEMBLED REGULATOR.
Step 1. Determine all available information from regu la -
tor's metal tag.
a. Serial number (5-digit).
b. Regulator “Type” or “Model” number.
c. Size (may have to observe body tap).
d. Spring range.
e. Trim designation number (if available).
Step 2. Determine construction of trim and soft goods.
a. What is fl uid?
b. What material is trim?

Step 3. With the information from Steps 1 and 2 above,
contact your local KM Sales Rep re sen ta tive for
the proper iden ti fi ca tion numbers to use, and the
parts costs.
METHOD C - NO PRODUCT CODE AVAILABLE
- AS SEMBLED REGULATOR IN SERVICE.
Step 1. Determine all available information from metal
tag using Step 1, Method B.
