| - | **The closest on the Circle Seal website** is a [[http://www.circle-seal.com/products/check_valves/c2900/index.html|2900 series cartridge check valve]]. \\ | ||
| - | 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> | ||
