BS EN 60534-2-3:2016

This standard BS EN 60534-2-3:2016 Industrial-process control valves is classified in these ICS categories:

• 25.040.40 Industrial process measurement and control
• 23.060.40 Pressure regulators

This part of IEC 60534 is applicable to industrial-process control valves and provides the flow capacity test procedures for determining the following variables used in the equations given in IEC 60534‑2‑1 :

1. flow coefficient C;

2. liquid pressure recovery factor without attached fittings F _L;

3. combined liquid pressure recovery factor and piping geometry factor of a control valve with attached fittings F _LP;

4. piping geometry factor F _P;

5. pressure differential ratio factors x _T and x _TP;

6. valve style modifier F _d;

7. Reynolds number factor F _R.
