Flow through a valve
Webthe line begins to level off as the flow becomes choked. This point is determined experimentally, by modeling the actual flow through a specific device, and is depicted by the bold curved line in the graph in figure 1. Figure 1. The point at which the flow becomes choked is determined by the FL value for liquid sizing, and the XT value for gas ... 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 ...
