Flow through valve

WebMar 11, 2024 · The valve coefficient, C v, is defined as the flow in gpm that flows through a valve with a pressure drop of 1psi across the valve (Δ Pv = 1 psi ). Cv is an important parameter that comes up in other modeling equations. It is specific to the valve you are using. C v = 29.9 d 2 K. 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 ...
