ordering spare parts
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 page 2� The
valve assembly number is shown on the valve
nameplate as, 'Shop Number'� Spare parts may
be ordered from any Emerson regional sales
office or representative�
all personnel working with Emerson products
should be trained adequately and thoroughly
familiar with the contents of the appropriate
instruction manual(s)�
Emerson cannot evaluate all conditions in
which the products may be used�
However, Emerson offers the following general
safety suggestions:
• Never subject valves to sharp impact loads.
Rough handling (striking, bumping, dropping,
etc�) may alter the pressure setting, deform
valve parts and affect seat tightness and valve
performance adversely� Striking a valve which
is under pressure can cause premature
actuation�
These precautionary statements are by no
means exhaustive�
Emerson cannot be expected to know, evaluate
and advise customers of all the possible
applications and operating conditions for
its products or of the possible hazardous
consequences which may result from the
misapplication or misuse of such products�
Consequently, the improper handling,
storage, installation, use or maintenance
of any Emerson product by a non Emerson
employee may void any Emerson guarantees or
warranties with respect to such product�

• When moving a valve, never use the lifting
lever to lift the valve�
• Always lower the system pressure to the
pressure level specified in the instruction
before making any adjustment to the valve�
Furthermore, always install a proper test rod
to gag an installed valve before making any
ring adjustments on the valve�
• Ear and eye protection should be used when
working on a valve which has pressure�
• Never stand in front of the discharge outlet
of a pressure relief valve which is under
pressure�
• Always stand to the side of and at a safe
distance from the valve discharge and use
extreme care when observing a valve for
leakage�
The above precautions and suggestions are
by no means exhaustive and the user should
always approach and use any pressure relief
valve with great care�
