Abstract

Pertains 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 F[L]; c) combined liquid pressure recovery factor and piping geometry factor of a control valve with attached fittings F[LP]; d) piping geometry factor F[P]; e) pressure differential ratio factors x[T] and x[TP]; f) valve style modifier F[d]; g) Reynolds number factor F[R].
