![]() ![]() ※3 For P1 and P2, please use pressure close to the valve. Please contact us if the fluid specification requires viscosity correction. ※2 Calculation of viscosity correction is necessary when the fluid is liquid and the kinematic viscosity is 20 mPa・s or more and the calculated Cv value is 0.01 or less. ![]() ![]() It is a standard for selection of valves, depending on the specific piping conditions and conditions of use, there is a possibility that actual results may differ from calculation results. 【Explanation of symbols】 QL : Liquid flow rate(h : hours) Qg : Gas flow rate in standard conditions (15℃ 0.1013 MPa abs) P1 : Primary absolute pressure ※3 P2 : Secondary absolute pressure ※3 t : Fluid temperature GL : Liquid relative density(Water = 1) Gg : Gas relative density(Air = 1) 【Notes on use】 ※1 Please handle the calculation result as reference value. ![]()
