GENERAL INFORMATION

1.1

Use

The following instructions are designed to assist in

the unpacking, installation, and maintenance as re-

quired 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

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 prop-

er precautions are not taken.

WARNING: Indicates that danger of death or severe

personal 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 appropri-

ate precautions are not taken.

NOTE: Indicates and provides additional technical in-

formation which may not be obvious, even to qualified

personnel.

Compliance with other notes, which may not be partic-

ularly emphasized, with regard to transport, assembly,

operation and maintenance and with regard to techni-

cal 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..

1.3 Protective clothing

Flowserve products are often used in problematic ap-

plications (e.g. under extremely high pressures with

dangerous, toxic or corrosive mediums). When per-

formng service, inspection, or repair operations, al-

ways ensure that the valve and the actuator are de-

pressurized and that the valve has been cleaned, and

that it is free of harmful substances. In such cases, pay

particular attention to personal protection (e.g. protec-

tive clothing, gloves, glasses etc).

1.4 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

dangers.

INSTALLATION

Before installing the valve, clean the pipeline of all con-

tamination, carbon deposits, welding chips, and other

foreign material. Carefully clean gasket surfaces to en-

sure a tight seal. Pipelines must be correctly aligned to

ensure that the valve is not fitted under tension.

Check the direction of fluid flow to ensure that the valve

is correctly installed. Flow direction is indicated by the

arrow attached to the body. All installation orientations

for fitting the valve into the pipeline are defined at the

end of this manual.

DANGER: To avoid serious injury, keep hands, hair,

clothing, etc away from the plug and seat when the

valve is working.

Connect the air supply and instrument signal lines.

Throttling control valves are equipped with a valve

positioner. Connections are marked for the air supply

and the instrument signal. Check that the actuator and

positioner can withstand the maximum air supply from

the network. The required air supply is indicated on a

sticker located on the actuator. An air regulator will be

necessary in certain cases in order to limit the supply

pressure. A filter is recommended unless the air sup-

plied is exceptionally clean and dry (air quality without

humidity, oil, or dust as per IEC 770 and ISA-7.0.0).

All connections must be completely tight.

.4 Use the bolts indicated in table I for installing the valve

in the pipeline, and then tighten alternately according

to good practice. The user must in all cases confirm

the capacity of the bolts to ensure a sufficiently tight

gasket seal for the expected service conditions.

STOP!
