1 GENERAL INFORMATION
1.1 Use
The following instructions are designed to assist in the
unpacking, installation, and maintenance as required for
Flowserve products. Product users and maintenance
personnel should thoroughly review this manual prior to
installing, operating, or performing any maintenance.
In most cases, Flowserve accessories, actuators and
valves are designed for specific applications (e.g. with
regard to medium, pressure and temperature). For this
reason, they should not be used in other applications
without first contacting the manufacturer.
1.2 Applicability
The following instructions are applicable to the main-
tenance and installation of Flowserve MaxFlo 3 control
valves. These instructions cannot claim to cover all
details of all possible product variations, nor can they
provide information for every possible example of in-
stallation, operation or maintenance. This means that
the instructions normally include only the directions to
be followed by qualified personal using the product for
its defined purpose. If there are any uncertainties in this
respect, particularly in the event of missing product-
related information, clarification must be obtained via
the appropriate Flowserve sales office. Flowserve User
Manuals are available at www.flowserve.com.
1.3 Terms related to safety
The terms DANGER, WARNING, CAUTION, NOTE are used
in this document to highlight particular dangers and/or
to provide additional information on points which may
not be clearly obvious.
DANGER: Indicates that death, severe personal injury
and/or substantial property damage will occur if proper
precautions are not taken.
WARNING: Indicates that danger of death or severe per-
sonal injury and/or property damage can occur if proper
precautions are not taken.
CAUTION: Indicates that minor personal injury and/or
serious damage to property can occur if the appropriate
precautions are not taken.
NOTE: Indicates and provides additional technical infor-
mation which may not be obvious, even to qualified per-
sonnel.
Compliance with other notes, which may not be particu-
larly emphasized, with regard to transport, assembly,
operation and maintenance and with regard to technical
documentation (e.g. in the operating instructions, prod-
uct documentation, or on the product itself) is essential,
in order to avoid faults, which can directly or indirectly
cause severe personal injury or property damage..
1.4 Protective clothing
Flowserve products are often used in problematic appli-
cations (e.g. under extremely high pressures with dan-
gerous, toxic or corrosive mediums). When performng
service, inspection, or repair operations, always ensure
that the valve and the actuator are depressurized and that
the valve has been cleaned, and that it is free of harm-
ful substances. In such cases, pay particular attention
to personal protection (e.g. protective clothing, gloves,
glasses etc).
1.5 Qualified personnel
Qualified personnel are people who on account of their
education, experience, training, and knowledge of rel-
evant standards, specifications, accident prevention,
and operating conditions have been authorized by those
responsible for the safety of the plant to perform the
necessary work, and recognize and avoid possible dan-
gers.
1.6 Spare Parts
Use only Flowserve original spare parts. Flowserve can-
not accept responsibility for any damages that occur
from using spare parts or fastening materials from other
manufacturers. If Flowserve products (especially sealing
materials) have been on store for long periods of time,
check them for corrosion or deterioration before putting
them into use.
1.7 Service / Repair
To avoid possible injury to personnel or damage to prod-
ucts, safety terms must be strictly adhered to. Modify-
ing this product, substituting non-factory parts, or using
maintenance procedures other than those outlined in
these Installation, Operation and Maintenance Instruc-
tions could drastically affect performance, be hazard-
ous to personnel and equipment, and may void existing
warranties. Between the actuator and the valve there
are moving parts. To avoid injury, Flowserve provides
pinch-point-protection in the form of cover plates, espe-
cially where side-mounted positioners are fitted. If these
plates are removed for inspection, service or repair
special attention is required. After completing work the
cover plates must be refitted. Apart from the operating
instructions and the obligatory accident prevention di-
rectives valid in the country of use, all recognized regu-
lations for safety and good engineering practices must
be followed.
