Introduction to Flow Characteristics - The Process Piping

Equal Percentage Flow Characteristic. In Equal Percentage Flow Characteristic, the change in flow per unit of valve stroke is directly proportional to the flow occurring just before the change in valve stroke is made.With an inherent equal percentage flow characteristic, the flow rate is small at the beginning of the stroke and increase to a larger magnitude at the end of the stroke.
