spare parts
emerson recommends spare parts as shown
on the outline drawing figure 1. When ordering
spare parts, the valve size, style and assembly
number and/or serial number should be
given together with set pressure, part name,
and reference number from figure 1. the
valve assembly number is shown on the valve
nameplate as 'Shop No'. Spare parts may be
ordered from any emerson regional sales office
or representative.
serviCe reCords
Service records should be completed before
a valve is returned to service. these records
are important and will provide guidance on
establishing time intervals between repairs as
well as providing the historical record of repairs
and service conditions. Well kept records will
be useful in predicting when to retire a valve
and which spare parts should be maintained in
inventory to ensure uninterrupted plant operation.

Warning
