1 Using Flowserve Valves, Actuators and Acces-
sories Correctly
1.1 General usage
The following instructions are designed to assist in
unpacking, installing and performing maintenance
as required on FLOWSERVE products. Product us-
ers and maintenance personnel should thoroughly
review this bulletin prior to installing, operating or
performing any maintenance.
In most cases FLOWSERVE valves, actuators and
accessories are designed for specific applications
with regard to medium, pressure and temperature.
For this reason they should not be used in other ap-
plications without first contacting the manufacturer.
1.2 Terms concerning safety
The safety terms DANGER, WARNING, CAUTION
and NOTE are used in these instructions to highlight
particular dangers and/or to provide additional infor-
mation on aspects that may not be readily apparent.
DANGER: indicates that death, severe personal injury
and/or substantial property damage will occur if proper
precautions are not taken.
WARNING: indicates that death, severe personal
injury and/or substantial property damage can occur
if proper precautions are not taken.
CAUTION: indicates that minor personal injury and/
or property damage can occur if proper precautions
are not taken.
NOTE: indicates and provides additional technical
information, which may not be very obvious even to
qualified personnel.
Compliance with other, not particularly emphasised
notes, with regard to transport, assembly, operation
and maintenance and with regard to technical docu-
mentation (e.g. in the operating instruction, product
documentation or on the product itself) is essential,
in order to avoid faults, which in themselves might
directly or indirectly cause severe personal injury or
property damage.
1.3 Protective clothing
FLOWSERVE products are often used in problematic
applications (e.g. extremely high pressures, danger-
ous, toxic or corrosive mediums). In particular valves
with bellows seals point to such applications. When
performing service, inspection or repair operations
always ensure, that the valve and actuator are depres-
surised and that the valve has been cleaned and is free
from harmful substances. In such cases pay particular
attention to personal protection (protective clothing,
gloves, glasses etc.).
1.4 Qualified personnel
Qualified personnel are people who, on account of their
training, experience and instruction and their knowl-
edge of relevant standards, specifications, accident
prevention regulations and operating conditions, have
been authorised by those responsible for the safety of
the plant to perform the necessary work and who can
recognise and avoid possible dangers.
