-Click on the 2900 series in the catalog section to the left on the their site. 
- 
-In the Products-Engineering-Terminology PDF; \\  
-<blockquote>Flow capability (Cv=0.55). 
-Flow capability indication commonly accepted by the valve industry. 
-The literal definition is that a component with a Cv of one (1); \\ 
-Can flow one (1) gallon of water with a ΔP of one (1) PSI. \\ 
-The calculated results from Cv equations must be considered reasonable approximations only.</blockquote>
