WebThe valve's flow coefficient, Cv, is a value that is determined by flow testing for each valve size. Full port valves will have a higher Cv than reduced port valves. ... The CV factor is the number of U.S. gallons per … WebThe valve flow coefficient according to the JIS standard, represents the flow capacity in US gallons/minute of 60° F pure water when it is flowing through the valve with a pressure difference of 1 psi at the specified …
WebNov 11, 2015 · A Flow Factor (Kv) is the flow coefficient in metric units that is defined as the flow rate in cubic meters per hour (m3/h) of water at a temperature of 16ºC with a pressure drop across the valve or any other restricting device of 1 bar. The Kv is related the head drop (Δh) or pressure drop (ΔP) across the valve with the flow rate (Q). (Kv ... WebMar 31, 2015 · The flow factor is the metric form and a simple conversion factor shown below can be used. Loss Factor, K: The loss factor is a constant directly proportional to the pressure drop across the component. As the K factor increases so does the resistance to flow. Pressure drop is in units of Psid and the fluid velocity is in units of ft/s.
WebFig. 1: Basic calculation for CV, where Q is the rate of flow (gallons per minute), SG is the specific gravity of the fluid, and P is the pressure drop across the valve (psi). Because air is compressible, CV must have additional factors built into the equations to compensate for that compressibility. For pneumatic applications, CV should be ...
