WebIf the inlet pressure (P 1) and valve flow area are fixed, the flow through a valve will normally rise as the downstream pressure (P 2) is reduced. The “Ideal” line in figure 1 illustrates this point, showing how liquid flow rises linearly when charted against the square root of the differential pressure across the valve divided by specific ... The flow coefficient of a device is a relative measure of its efficiency at allowing fluid flow. It describes the relationship between the pressure drop across an orifice valve or other assembly and the corresponding flow rate. Mathematically the flow coefficient Cv (or flow-capacity rating of valve) can be expressed as : where:

WebAn equal percentage valve delivers 8 gpm of water when the valve is 50% open (x=0.5). When the valve is 60% open (x=0.6), the flow rate increases to 16 gpm. Estimate the flow rate through the valve when it is 70% … WebCv is directly rated to flow rate, so the higher the Cv, the more flow that can travel through the valve. Cv can be calculated based on the below equations, one for liquid, and one …
