Control Valve Equal Percentage Curve at Ron Gerald blog

Control Valve Equal Percentage Curve. The relationship between valve stem position and the flow rate through a control valve is described by a curve called the valve’s flow. Comparing linear and equal percentage valves, a linear valve might have a 25% valve opening for a certain pressure drop and flowrate, whilst an equal percentage valve might have a 65% valve opening for exactly the same conditions. By observing the curve for the equal percentage valve, it can be seen that, although a linear relationship is not achieved throughout its whole travel, it is above 50% of the flowrate. The equal percentage valve plug produces the same percentage change in flow per fixed increment of valve stroke at any location on its. What is an equal percentage control valve? Equal increments of valve travel produce equal percentage changes in the existing c v. A control valve with “linear” trim will exhibit consistent responsiveness only with a constant pressure drop, while “equal percentage” trim is.
