WebBall Valves The below CV values are used to give an indication of flow rates for ball valves. CV value is an imperial measure of flow in US gallons per minute of water at 60° fahrenheit with a pressure drop of 1 psi across the valve. This is used as a guide and is not a linear progression. V Port Ball Valves Flow Rate (CV) WebCv = Cv_saturated (1 + 0.00065 (50oF) =1.0325 Cv_saturated Flow Coefficient - Cv - Saturated Wet Steam Saturated wet steam includes non evaporated water particles reducing the "steam quality" and a flow coefficient for very wet saturated steam should be multiplied with a correction factor: Cv = Cv_saturated ζ1/2 (4) where ζ = dryness fraction opensubtitles the last challenge legendas pt
