Presents equations for predicting the flow of compressible and incompressible fluids through control valves. The equations for compressible fluids are for use with gas or vapor and are not intended for use with multiphase streams such as gas-liquid, vapor-liquid or gas-solid mixtures. The equations for incompressible flow are based on standard hydrodynamic equations for Newtonian incompressible fluids and are not intended for use when non-Newtonian fluids, fluid mixtures, slurries, or liquid-solid conveyance systems are encountered.

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); & pressure drop ratio factors (Xt & Xtp). The standard is intended for control valves used in flow control of process fluids & is not intended to apply to fluid power components as defined in the National Fluid Power Association Standard NFPA T.3.5.28-1977.
