Control Valve Capacity Test Procedures
Organization:
ISA - International Society of Automation
Year: 2008
Abstract: This test standard utilizes the mathematical equations outlined in ANSI/ISA-75.01.01 (IEC 60534-2-1 Mod)-2007, Flow Equations for Sizing Control Valves, in providing a test procedure for obtaining the following:
a) Valve flow coefficient, C (Cv, Kv)
b) Liquid pressure recovery factors, FL and FLP
c) Reynolds Number factor, FR
d) Liquid critical pressure ratio factor, FF
e) Piping geometry factor, FP
f) Pressure drop ratio factor, xT and xTP
g) Valve style modifier, Fd
This standard is intended for industrial process control valves used in flow control of Newtonian fluids. See 4.2 for more information regarding specific valve styles.
Purpose
The purpose of this standard is to support ANSI/ISA-75.01.01 (IEC 60534-2-1 Mod)-2007, Flow Equations for Sizing Control Valves, and ANSI/ISA-75.11.01-1985 (R2002), Inherent Flow Characteristic and Rangeability of Control Valves, by providing procedures for testing control valve capacity and related flow coefficients for both compressible and incompressible Newtonian fluids. This standard also provides a procedure to evaluate the major data to calculate the coefficients.
