Valve Cv Explained

Valve Cv Explained. The valve flow coefficient, cv, is the number of u.s. What is the cv of a valve?

= valve sizing coefficient determined experimentally for each style and size of valve, using water at standard conditions as the test fluid ∆p = pressure differential in psi g = specific gravity of fluid (water at 60°f = 1.0000) thus, c v is numerically equal to the number of u.s. In this video, we define and illustrate the concept of valve cv. In other words, flow capacity is a measure of efficiency at allowing liquid to flow.
