Flow characteristic of butterfly valve
Websignificant impact on the actual installed valve flow characteristic. The deviation from the inherent flow characteristic is a function of a property called Valve Authority. It is defined as the ratio of the full flow valve pressure drop to the system pressure drop (including the valve). N = ∆Pvalve ÷ ∆Psystem where: N = Valve Authority WebInstalled Control Valve Flow Characteristics. When valves are installed with pumps, piping and fittings, and other process equipment, the pressure drop across the valve will vary as the plug moves through its travel. …
