WebCv for FLUIDS Cv for liquids is the volume of 68°F water in U.S. gallons per minute that passes through a valve at a pressure drop of 1 PSI. Flow for a given Cv is typically calculated from the following formula. Where: Q = Valve flow rate in gallons per minute (US GPM) ΔP = Difference between upstream and downstream pressure in The flow coefficient of a device is a relative measure of its efficiency at allowing fluid flow. It describes the relationship between the pressure drop across an orifice valve or other assembly and the corresponding flow rate. Mathematically the flow coefficient Cv (or flow-capacity rating of valve) can be expressed as : where:
