Book Description
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.
