The Cv is more or less how big is the hole. Kv Cv Flow Coefficient Valvias Go to online calculation of the Flow coefficient Cv and Kv Each valve has its own flow coefficient. This depends on how the valve has been designed to let the flow going through the valve. Therefore, the main differences between different flow coefficients come from the type of valve, and of course the opening position of the valve. Instrumentación Hoy: CONVERSIÓN Kv Cv Nota: Kv es lo mismo que el Cv pero en unidades métricas, la equivalencia es Cv = 1,156 x Kv.

This is our valve C v calculator. It allows you to calculate the flow or C v (flow coefficient) to make the relationship visible between the pressure drop (the difference in pressure between two points in a network transporting a liquid or gas) and the flow rate. The use of this flow coefficient (C v) calculator leads to a standard calculation to compare valve capacities ... Calculate the flow factor – Bürkert Fluidic Calculator Difference between Cv value & Kv factor. The often equated Cv value is the US measurement unit, which is given in USG min (US Gallon per minute), and can therefore not be compared with the Kv factor. Conversion formulas exist for these values: Kv = 0.857 * Cv Cv = 1.165 * Kv. Formulas for calculating the flow factor for various aggregate states Flow Calculator Quickly & Accurately Calculate the flow ... Select a media, enter your data and let the calculator do the rest. It features conversion calculators to help you convert between metric & imperial values. calculation Authority valve kvs kv cv coefficient pressure ... KV is the flow that generates a pressure drop of 1 bar at a given degree of openness . KVS is the flow that generates a pressure drop of 1 bar when the valve opening is maximum. The calculation of valve's KV can therefore be related to the pressure loss Conversion tool kV KVS and CV valve in mecaflux.
