The valve flow coefficient Cv is expressed as a percentage of the maximum possible flow rate, considering the corresponding pressure drop. 考虑到相应的压降,阀门流量系数Cv表示为最大可能流量的百分比。 Cv, also known as ‘Valve Flow Coefficient’, is a practical definition used to measure the flow ...
Valve flow coefficient, abbreviated as Cv (in the United States) or Kv (in Europe), is a numerical value used to quantify the flow capacity of a valve or other fluid control device. It is a parameter in fluid dynamics and is used to describe how well a valve can control the flow of...
In simpler terms, the larger the opening in a valve, the larger the Cv. As a valve is opening, the Cv increases until the valve is fully open, where it reaches its highest possible Cv, or 100% open Cv.Example of Valve Flow Coefficient (Cv)...

A valve (2) comprising a valve body (4) including a first end (8) and a second end (10) spaced apart along a longitudinal axis (12), a central portion (6) disposed between the first end and the second end, wherein the first end and the second end define a first flow passageway ...
The values in this vector correspond one-to-one with the elements in the Valve area vector, Orifice area vector, Cv flow coefficient vector, or Kv flow coefficient vector parameters. Dependencies To enable this parameter, set Opening pressure specification to Pressure differential and either: ...
