Marking of general purpose industrial valves

This technical specification establishes comprehensive requirements for the identification and marking of general purpose industrial valves. It outlines the mandatory data fields that must appear on valve bodies to ensure clarity and traceability throughout their lifecycle. The defined marking elements include information related to manufacturer identity, material classification, pressure ratings, and flow direction indicators. Specific attention is given to the legibility, durability, and positioning of these marks on various valve types and sizes. The guidelines ensure consistent application across different manufacturing facilities, facilitating easier maintenance, inspection, and safety assessments during operation and installation. Adherence to these marking protocols supports interoperability within industrial systems and helps prevent operational errors caused by misidentification. The document serves as a reference for quality assurance processes, guiding producers in implementing standardized labeling practices that align with industry expectations for safety and reliability in fluid control applications.
