Popis
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 :
-
flow coefficient C;
-
liquid pressure recovery factor without attached fittings F L;
-
combined liquid pressure recovery factor and piping geometry factor of a control valve with attached fittings F LP;
-
piping geometry factor F P;
-
pressure differential ratio factors x T and x TP;
-
valve style modifier F d;
-
Reynolds number factor F R.
