Uses mathematical equations covered in ANSI/ISA-S75.01, Flow Equations for Sizing Control Valves, in supplying a test method to obtain:- Valve flow coefficient, Cv; Liquid pressure recovery factors, FL and FLP; Reynolds Number factor, FR; Liquid critical pressure ratio factor, FF; Piping geometry factor, Fp; and pressure drop ratio factors. Intended for control valves used in flow control of process fluids and is not intended to apply to fluid power components as defined in the National Fluid Power Association Standard NFPA T.3.5.28-1977.
