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.

programs

field service

emerson field service provides on-site, in 
line testing and repair capability for all types 
of pressure relief devices. it is strongly 
recommended that on new installations, a 
emerson service engineer be present for 
assembly and testing of safety valves.

parts

emerson will help you establish the right mix 
of on-site spares with our own distribution and 
manufacturing support.

training

emerson offers intensive factory or on-site 
training seminars to improve maintenance 
and application skills.

Warning

The safety of lives and property often depends 
on the proper operation of the safety valves. 
Consequently, the valves should be kept clean and 
should be tested periodically and reconditioned to 
make sure they function properly.

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.
