GB/T 20818.21-2020

This standard defines a generic structure for listing properties of automated valves used in industrial-process measurement and control, enabling standardized electronic data exchange between manufacturers, suppliers, and system integrators. It is applied in the manufacturing and procurement of automated valves for process industries such as chemical, oil and gas, and power generation, where consistent data formats are essential for cataloging, selection, and integration into control systems. The standard ensures interoperability by specifying common data elements and structures for valve attributes like size, pressure rating, and actuation type in digital catalogs.
