As an example, this upper line could represent a 6 inch globe valve at 80% open which would have a Cv of about 250. A 4 inch high performance butterfly valve operating at around 70% open would also have a Cv of about 250. Although both valves have the same flow capacity ...

WebThe Cv tells you how to properly size your valve so it has minimal effect on the hydraulic efficiency you’ve engineered into your system. It is a number published by the valve manufacturer that describes the number of U.S. gallons that can pass through a valve (in a fully open position) at a pressure drop of 1 PSI. WebIf you have the molecular weight of your gas, SG=MW/28.97 (MW of air is 28.97). IMO a much easier way to calculate specific gravity, since density varies with T and P but SG and MW do not, so you don’t have to bother compensating for flow conditions. SG is one of those properties that shouldn’t change depending on your T and P. holiday emails to staff
