1. Scope
2. Basic definitions
2.1 Terminology
2.2 Flow coefficient
2.3 Inherent flow characteristic
2.4 Inherent rangeability
2.5 Relative flow coefficient (0)
2.6 Relative travel (h)
3. Typical inherent flow characteristics
4. Permissible deviations between actual and manufacturer-
stated inherent flow characteristics
To establish criteria for adherence to manufacturer-defined flow characteristics and to specify the statement of typical control valve inherent flow characteristics and inherent rangeabilities is the purpose of this standard. Uses the basic definitions from ISA-75.05-1983 and defines specific terms related to flow characteristic and rangeability.
