WebFlow coefficient (Cv) is defined as the number of gallons per minute (gpm) at 60°F that will pass through a full open valve with a pressure drop of 1 psi. Simply stated, a control valve which has a Cv of 12 has an effective port area in the full open position such that it passes. 12gpm of water with 1 psi pressure drop. 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: … See more The metric equivalent flow factor (Kv) is calculated using metric units : where Kv is the flow factor (expressed in m ·h ).
