GENERAL INFORMATION

Use

The following instructions are designed to assist in the

unpacking, installation, and maintenance as required for

Flowserve products. Product users and maintenance per-

sonnel should thoroughly review this manual prior to in-

stalling, 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.

Applicability

The following instructions are applicable to the mainte-

nance and installation of Valtek ShearStream HP control

valves. These instructions cannot claim to cover all details

of all possible product variations, nor can they provide in-

formation for every possible example of installation, opera-

tion or maintenance. This means that the instructions nor-

mally 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.

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 precau-

tions 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 seri-

ous damage to property can occur if the appropriate pre-

cautions are not taken.

NOTE: Indicates and provides additional technical informa-

tion which may not be obvious, even to qualified person-

nel.

Compliance with other notes, which may not be particularly

emphasized, with regard to transport, assembly, operation

and maintenance and with regard to technical documenta-

tion (e.g. in the operating instructions, product documenta-

tion, or on the product itself) is essential, in order to avoid

faults, which can directly or indirectly cause severe person-

al injury or property damage..

Protective clothing

Flowserve products are often used in problematic applica-

tions (e.g. under extremely high pressures with dangerous,

toxic or corrosive mediums). When performng service, in-

spection, 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 harmful substances. In

such cases, pay particular attention to personal protection

(e.g. protective clothing, gloves, glasses etc).

Qualified personnel

Qualified personnel are people who on account of their

education, experience, training, and knowledge of relevant

standards, specifications, accident prevention, and operat-

ing conditions have been authorized by those responsible

for the safety of the plant to perform the necessary work,

and recognize and avoid possible dangers.

Spare Parts

Use only Flowserve original spare parts. Flowserve cannot

accept responsibility for any damages that occur from us-

ing spare parts or fastening materials from other manufac-

turers. 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.

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 Instructions could

drastically 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

injury, Flowserve provides pinch-point-protection in the

form of cover plates, especially where side-mounted posi-

tioners are fitted. If these plates are removed for inspection,

service or repair special attention is required. After com-

pleting work the cover plates must be refitted. Apart from

the operating instructions and the obligatory accident pre-

vention directives valid in the country of use, all recognized

regulations for safety and good engineering practices must

be followed.
