Flow rate through a valve
While knowing the pipe connection size and orifice diameter is necessary for valve sizing, calculating the media flow rate and pressure drop across the valve will give you more accurate sizing information. What Is Flow Rate? Valve Size Chart (Cv) Cv Value Calculator for Fluids Cv Value Calculator for Gases See more The valve flow coefficient, or flow rate, is the rate at which media flows through the valve, and how much the pressure of the flow changes (drops) across the valve. The state and … See more For a quick reference, here are the approximate Cv values (in psi) for a range of standard valve sizes. See more The Cv value for fluids can be found using the following formula: Where: Cv = Valve flow coefficient Q = Volumetric flow rate (SCFH – Standard Cubic Feet/Hour) P1 = Inlet Pressure (psia) P2 = Outlet Pressure (psia) T = … See more
