ISA 75.02.01 – Control Valve Capacity Test Procedure
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
