In this section, we explain the different certificates that can accompany valves and other industrial components. These include EN 10204 certificates (types 3.1 and 3.2), ATEX certification, and standards like UNE, ISO, or BS. We clarify what they mean, when they are required, and how they affect the safety and quality of products in high-pressure sectors like hydrogen and oil & gas. You will also find information on CE Marking, Lloyd’s, DNV, TÜV, and Classification Society certificates to help ensure compliance with the most stringent standards.
