Cv of 2 ball valve
WebΔP is the pressure drop across the valve (expressed in psi). In more practical terms, the flow coefficient Cv is the volume (in US gallons) of water at 60 °F (16 °C) that will flow per minute through a valve with a pressure drop of 1 psi (6.9 kPa) across the valve. The use of the flow coefficient offers a standard method of comparing valve ... WebExample of Valve Flow Coefficient (Cv) Below is a Valve Cv chart showing flow curves for two different valves: a 2-inch and 3-inch Kimray back pressure regulator. As the stem opens, the Cv increases. The maximum …
