Title (German)

Stellventile für die Prozessregelung - Teil 2-3: Durchflusskapazität - Prüfverfahren (IEC 60534-2-3:2015); Deutsche Fassung EN 60534-2-3:2016

Overview

This part of the International Standard series 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: a) flow coefficient C; b) liquid pressure recovery factor without attached fittings FL; c) combined liquid pressure recovery factor and piping geometry factor of a control valve with attached fittings FLP; d) piping geometry factor Fp; e) pressure differential ratio factors xT and xTP; f) valve style modifier Fd; g) Reynolds number factor FR. In the present revision, among other things, the requirements for the measuring equipment for pressure, flow and temperature have been defined more precisely and new informative annexes on calculation data, control valve type factor, laminar flow as well as on test methods and calculation of FL and FP have been added. The responsible committee is DKE/K 963 "Stellgeräte für strömende Stoffe" ("Actuators with flowing substances") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
