IEC EN 60534-2-3 Industrial Process Control Valves - Flow Capacity Test

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 60534-2-3 testing. IEC EN 60534-2-3 applies to industrial process control valves and provides flow capacity test procedures to determine the following variables used in the equations given in IEC EN 60534-2-1:

• Flow coefficient C;
• Fluid pressure recovery factor without FL fittings;
• Combined fluid pressure recovery factor and pipe geometry factor of a control valve with FLP fittings;
• Pipe geometry factor FP;
• Pressure differential ratio factors xT and xTP;
• Valve style modifier Fd;
• Reynolds number factor FR.

Throttle valves are used to control pressure differences in the test section. There are no restrictions on the style of these valves. However, its own flow valve must have sufficient capacity and may be larger than the nominal size of the test specimen, so this capacity must be ensured. In test standards for compressible flow, the desired flow can be achieved.

All pressure and differential pressure measurements should be made using instruments with an accuracy rating of ± 2% of the actual output reading. Pressure gauges should be calibrated as often as necessary to maintain specified accuracy.

If separate pressure measurements (p1, p2) are used instead of a single differential pressure measurement (∆p), care should be taken to select instruments that are accurate enough to allow the calculated pressure difference value (p1 – p2) to be known with an error.
