Industrial-process control valves - Part 2-4: Flow capacity - Inherent flow characteristics and rangeability
IEC 60534-2-4:2009 applies to all types of industrial-process control valves. It defines how to state typical control valve inherent flow characteristics and inherent rangeabilities. It also defines how to establish criteria for adherence to manufacturer-stated flow characteristics. This edition constitutes a technical revision. The main changes with respect to the previous edition are:- update the normative references;- delete the terminology included in IEC 60534-1;- transform the previous Note 1 in Clause 6;- redraw the graphics;- delete the previous Figure 3.
