WebAt low flow rates – where the valve is nearly closed – any small movement of the valve stem will have a relatively large effect on fluid flow. However, at high flow rates, a much greater stem motion will be required to achieve a comparable effect on fluid flow. ... = Rangeability coefficient of equal-percentage trim. Another common inherent ... WebAug 4, 2012 · The term rangeability R is used for the ratio Q max /Q min, i.e. the ratio of the maximum to minimum rates of controlled flow. Thus, if the minimum controllable flow is 2.0% of the maximum controllable flow, then the rangeability is 100/2.0=50. Valves are … Figure 16-1.
