The Use of Control Valve Sizing Equations with Simulation

WebIn a general sense, the valve flow coefficient, or C v is a number that represents a valve’s ability to pass the flow through it. The bigger the value of Cv, the more will be the flow through the valve with a given pressure drop.Also, the valve C v is directly related to the valve opening. The larger the valve opening, the larger is the C v.The highest possible … WebControl valve flow characteristic shows the relationship between the relative flows of the process media flowing through the control valve and valve opening. It’s opening under the condition of constant pressure difference at both ends of the valve. “Flow characteristic” is a general term and should always designate either the inherent ...
