cv to kv

Flow Coefficient, Cv, to Flow Factor, Kv, Converter – My ... Flow coefficient, Cv, and Flow Factor, Kv, are values used to specify the hydraulic capacity of a control valve. Flow coefficient is an imperial measurement and is defined as: the flow of water through a valve at 60°F in US gallons minute (gpm) at a pressure drop of 1lb in² . Kv Cv Flow Coefficient Valvias Kv is the flow coefficient in metric units. It is defined as the flow rate in cubic meters per hour [m3 h] of water at a temperature of 16º celsius with a pressure drop across the valve of 1 bar. Cv is the flow coefficient in imperial units. Converting Between Cv, Kv and K | Neutrium There are several common ways to express the losses caused by pipe fittings and equipment. Depending on the calculation programs or methods available and engineer may require to convert between one form or another. This article details the equations required to convert between the resistance coefficient and flow coefficient methods (K, Cv and Kv). Control Valve Relation between Cv and Kv | Cv = 1.156Kv Kv = 0.864 Cv At a particular percentage of opening of valve giving Cv = 1 will pass 1US GPM ( at 60 °F) and a pressure differential of 1 psi upstream and downstream across the valve. For the same pressure conditions, if we increase the valve opening to create Cv = 10, It will pass 10 US GPM provided 1 psi pressure drop across the valve (remains same). Conversion calculation Cv and Kv valve flow coefficients Cv and Kv are 2 coefficient allowing to relate the pressure drop through a valve to the flowrate of fluid going through. Cv is commonly called the flow coefficient and Kv is commonly called the flow factor. They have very similar meaning but not exactly the same definition. What does the Cv of a valve mean ... Cv and Kv Flow Coefficients Pipe Flow Software The Cv (or Kv) flow coefficient of a control valve is usually stated for the fully open flow condition. The Cv (or Kv) flow coefficient will be less when the valve is partly closed. In an actual system it is important to select a control valve which has an appropriate Cv (or Kv) flow coefficient for the actual valve position that will be used.
