Control Valve Dp. The valve authority expresses the ratio between pressure drop across the control valve compared to total pressure drop across the whole system. When you get to the valve outlet you know p2, the pressure immediately downstream of the valve. Monsen discusses the correct method for determining the control valve sizing pressure drop when the system already exists or has been designed. The actual pressure drop across the control valve is the difference between the. Pressure drop, or pressure loss, is the difference in pressure as measured between two points in a pipe with flowing fluid. There is a procedure for making the calculations that determine what the differential pressure (∆p) is for a control valve in a given system at specific flow rates. The pressure drop across the control valve is the difference in the pressure system between two points in a pipeline with flowing fluid. Specific to control valves, it is the difference between the inlet pressure and outlet pressure. Our guest writer jon f. This pressure differential or delta p is the inlet minus the outlet pressure. When determining the control valve pressure drop to use in a control valve sizing calculation, there are three possible scenarios. When selecting a valve, remember that every control valve has friction to overcome before the valve stem moves and changes the pressure drop across it.
