1 Scope

This part of GB/T 20818 stipulates.

- The Common Data Dictionary (CDD) has a collection of various automatic valves, including the characteristics of control valves, automatic on/off valves and process regulators description;

- Compliant with IEC 61987-10, the common operation attribute list (OLOP) and equipment attribute list (DLOP) of the final control element structure.

The general structure of OLOP and DLOP contains the most important blocks for the final control element. The relevant blocks for a specific device type are in

Described in other parts of the IEC 61987 series of standards. Similarly, this section does not involve device attributes. For example, globe valve and quarter stroke

The OLOP and DLOP of the valve are specified in IEC 61987-22.

Note. In the classification (see Figure 1), the "final control element" has only special automatic valves and process regulators. In practice, there are other specialized equipment

Part of consideration.
