2 Safety Information
2.1 Intended Use
ARGUS ball valves are used as shut-off devices, e.g. in pipework or at attached vessels in the field for transport and
processing of liquids, gases and solid-containing fluids.
The valve design takes into account international and national regulations, such as the European Directive for Pressure
Equipment 2014/68/EU, EN12516, AD 2000 Regulations, API 6D and ASME/ANSI B16.34 and others depending on
the specified application and legislation.
Proper use of the ball valves will never exceed the application limits
such as instructed on the valve nameplate, by additional marking on
the product, in the product specification, specific provisions, or in
this manual.
Failure to comply with this information is considered to be misuse,
which can be the cause of personal injury or product damage or
malfunctioning, which are not covered by the manufacturer’s
warranty.
Comprehensive Quality Assurance, certified in accordance with ISO 9001 e.g., has always been a determining factor
within the overall process of design, procurement, manufacturing and marketing at all Flowserve sites.
All relevant laws, directives, standards and specifications are adopted for specific applications of the valves.
2.2 Operating Limits of the Ball Valve – Refer to the Nameplate
ARGUS ball valves are generally designed for special applications. Type, model, material selection, nominal size,
special features, attachments, accessories and valve qualification are adapted to the specified operating conditions.
This results in application limits concerning fluids (media), pressure, temperature and other application and
environmental conditions for each ball valve.
The metallic type plate, or “manufacturer nameplate”, fixed to the ball valve provides information on these application
limits. Also refer to Chapter "Nameplate: Identification of the Ball Valve".
The specified operating limits as shown on the nameplate, must never be exceeded.
2.3 Responsibility of Plant Engineering and Operation
ARGUS ball valves are often installed as safety-relevant components in plants and systems. Risks due to incorrect
installation or unintended use and operation must be prevented.
The qualified personnel entrusted with the assembly of the system are responsible for ensuring that the ball valve is
permanently integrated safely into the system in accordance with the relevant legal framework, standards, specification
and in accordance with these instructions.
The plant operator is responsible for commissioning and continuous operation of the ball valve and must guarantee the
correct application of the valve. In particular, the operating limits of the ball valve must be observed.
Any hazards resulting from the operation of the valve, e.g. due to extreme surface temperatures, must be avoided.
Comprehensive protection of people and the environment must be ensured. Observe all local and national
regulations on occupational safety and health.
2.4 Qualified Personnel for Installation and Operation
All personnel involved in the operation, installation and maintenance of the unit must be qualified to carry out the work
involved. If the personnel in question does not already possess the necessary knowledge and skill, appropriate training
and instruction must be provided. If required, the operator may entrust the manufacturer / supplier to provide applicable
training.
Always co-ordinate repair activities with operation and health and safety personnel, and follow all plant safety
requirements and applicable safety and health laws and regulations.
