WebCalculate required control valve capacity (Cv or Kv) for Minimum, Normal, Maximum and one additional flow condition. Engineering units are by default set to US units, but can be easily changed to SI units. Comprehensive instructions. Based on ANSI/ISA-75.01.01 (IEC 60534-2-1 Mod) -2012 "Flow Equations for Sizing Control Valves." 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 ...
