ISA 75.11-1985 (R1997) [ Withdrawn ] Inherent Flow Characteristic & Rangeability of Control Valves

standard by The International Society of Automation, 04/01/1985

Full Description

Formerly S75.11. Defines typical control valve inherent flow characteristics and inherent rangeabilities and establishes criteria for adherence to manufacturer-specified flow characteristics. This standard uses the basic definitions from ISA-S75.05 and also defines specific terms related to flow characteristic and rangeability. A table listing inherent flow characteristic deviations and sample plots of relative flow coefficient versus relative travel are also given.
