WebSelect a valve that meets the higher 1.52 Cv rating. Note: Many fluid power engineering and data resources have flow charts to simplify this process, but in the absence of those charts, this information should help with sizing pneumatic valve requirements. Air Flow Rates: WebA K v value is defined as the rate of flow of water in m 3 /hr and 4°C at a pressure drop of 1 bar across the equipment. K v relates to pressure drop and flow rate via the following expression: \displaystyle K_v = Q \sqrt { \frac {SG} { \Delta P}} K v = Q ΔP SG. Where Q is in m 3 /hr and ΔP is in bar. Thus for a given K v, ρ and Q the ...
