1. General Information
1.1. Using
The following instructions are designed to assist in unpack-
ing, installing and performing maintenance as required on
Flowserve products. Product users and maintenance person-
nel should thoroughly review this bulletin prior to unpacking,
installing, operating, or performing any maintenance. In
most cases, Flowserve valves, actuators and accessories
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 con-
tacting the manufacturer. The product Installation, Operation,
and Maintenance Instructions provides important additional
safety information.
1.2. Applicability
The following instructions are applicable to the maintenance
and installation of Flowserve Valtek Mark One and Mark Two
globe and angle body design control valves. These instruc-
tions cannot claim to cover all details of all possible product
variations, nor can they provide information for every possi-
ble example of installation, operation or maintenance. This
means that the instructions normally include only the direc-
tions 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 appropri-
ate Flowserve sales office. All Flowserve User Manuals are
available at www.flowserve.com.
1.3. Terms Concerning Safety
1.3.1. The safety terms DANGER, WARNING, CAUTION and NOTE
are used in these instructions to highlight particular dangers
and/or to provide additional information 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 precau-
tions are not taken.
CAUTION: Indicates that minor personal injury and/or proper-
ty damage can occur if proper precautions are not taken.
NOTE: Indicates and provides additional technical informa-
tion, which may not be obvious, even to qualified personnel.
1.3.2. Compliance with other notes, which may not be particularly
emphasized, with regard to transport, assembly, operation
and maintenance and with regard to technical documentation
(e.g. in the operating instructions, product 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
DANGER: Flowserve products are often used in problem-
atic applications (e.g. under extremely high pressures with
dangerous, toxic or corrosive mediums). When performing
service, inspection, or repair operations, always ensure that
the valve and actuator are depressurized and that the valve
has been cleaned and is free from harmful 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
training, experience and instruction and their knowledge of
relevant standards, specifications, accident prevention reg-
ulations and operating conditions, have been authorized by
those responsible for the safety of the plant to perform the
necessary work and who can recognize and avoid possible
dangers. Contact your local Flowserve representation for a
schedule of training schools.
1.6. Spare Parts
Use only Flowserve original spare parts. Flowserve cannot
accept responsibility for any damages that occur from using
spare parts or fastening materials from other manufactures.
If Flowserve products (especially sealing materials) have
been on store for long periods of time check them for corro-
sion 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. Modifying
this product, substituting non-factory parts, or using main-
tenance procedures other than those outlined in these Instal-
lation, Operation, and Maintenance Instructions could dras-
tically affect performance, be hazardous to personnel and
equipment, and may void existing warranties. Between the
actuator and the valve there are moving parts. To avoid in-
jury, Flowserve provides pinch-point-protection in the form
of cover plates, especially 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 direc-
tives valid in the country of use, all recognized regulations
for safety and good engineering practices must be followed
.
