Flow Coefficient Information - Emerson

1 Flow Coefficient InformationScope The values given below are applicable to Floating Ball Valve/Tru nnion Mounted Ball Valve, when the ball valve is in full open Coefficient Cv It is the full capacity flow rate through the valve in US gallons/min. of water at 60 F with a pressure drop of 1 Coefficient Kv Volumetric flow rate of water at a temperature between 5 C (40 F) and 40 C (104 F) passing through a valve and resulting in a pressure loss of MPa (1 bar; PSI). Kv is expressed in SI units of cubic meters per hour. Kv = Cv / (in USGPM*) for Full Bore Ball ValvesSize/Class#150#300#600#900#1500#25 00 MmInch15 201817 15151420 4944 40 373734251 9484 75 696964401 239224201181181164502 449411358323323191803 122210549479188354571004 2374209517881743160610031506 5247519644934320358624642008 101929788868682626887517225010 1654616106139851360211042818130012 24735241162160620318165131204835014 3000328710268812301119908---40016 4085539267365973194426701---45018 5280851588478454230534492---50020 67883656506069953471------60024 101990991649119880055------65026 118518114449107461---------70028 138680134349126710---------75030 163044158125147549---------90036 234261222624205959---------Document No.
