Flow Control Valve Pump Curve. overlaying the system curve on the pump curve indicates how the pump will perform given a specific flow rate and head pressure, depending on the position of the pump control valve and the impeller diameter. Doubling the rangeability of the control valve increases the maximum flow rate to a small amount. The flatter the pump curve, the larger the maximum flow rate at a given relative pressure drop of the control valve. a comparison of those figures demonstrates the great influence of the pump’s characteristic on the maximum flow rate: in water systems, the pump characteristic curve means that as flow is reduced, the upstream valve pressure is increased (refer. the principal curves that define a pump’s operating characteristics are the performance curve (blue), the power curve (green), and the efficiency curve (red). in this chapter, we introduce a process pipeline model and calculation procedure enabling the quick and accurate prediction of control. control valve flow characteristics. For continuous process control valves, there are three inherent flow characteristics that can be specified when ordering. 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.
