Pneumatic driven butterfly valve Cylinder air consumption calculation. 

● Double action air consumption (L/min)= cylinder (opening volume + closing direction volume) ×[(air supplying Pressure(Kpa)÷101.3)/101.3]×time/min。
● Single action air consumption (L/min)= cylinder opening volume×(air supplying Pressure(Kpa)+ 101.3)÷ 101.3)×time/min。
