Control Valve Capacity Test Procedure
standard by The International Society of Automation, 04/01/1996
Full Description
Formerly S75.02. Provides a test procedure for obtaining the following factors for sizing control valves: 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 (XT and XTP). The standard is 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.
