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.
.

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

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).
.5
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.
.6
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.
.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 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.
