The flow characteristic of a control valve is the relationship between the flowing quantity of fluid through the valve and the valve stem travel from closed (0%) to the fully open (100%) position. Normally the relationship is represented as in Figure below, where the valve lift and capacity are stated as percentages of maximum travel and the flow coefficient of the fully open valve.
