Risk of injury due to trapped pressure!
Pressure trapped in the inside of the Argus Ball Valve may cause severe injury.
Before removing and/or loosening the drain plug, operate the Argus Ball Valve several
times so that the trapped pressure can escape.
1.4 Argus Ball Valve as Pressure Equipment
The design of Argus Ball Valves takes all relevant laws, directives, standards, and
specifications into account, such as the European Directive for Pressure Equipment
2014/68/EU, EN 12516, AD 2000 Regulations, API 6D and ASME/ANSI B16.34 and others,
depending on the specified application.
The careful selection, design and calculation of materials as well as quality assurance
performed during materials procurement, in production and on finished products ensure the
elimination of pressure-related hazards when the Argus Ball Valves are used as intended.
As a manufacturer, Flowserve Flow Control GmbH applies the conformity assessment
procedure according to module H (Article 14 of European Pressure Equipment Directive
2014/68/EU), i.e., “Comprehensive Quality Assurance” as described in Appendix III,
Paragraph 11.
Argus Ball Valves are marked according to the provisions of the European Pressure
Equipment Directive with the CE mark as well as the identification number of the notified
conformity assessment body.
For the Argus Ball Valves, which are covered by the provisions of the European Pressure
Equipment Directive 2014/68/EU, the EU declaration of conformity is part of this operating
manual.
