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.
