How to calculate control valve diameter size ,let’s give you some brief introduction about how to confirm whether the diameter is suitable for the control valve. Control valve working condition：Medium:Liquid nitrogen，t=33℃，λ=5.9×10^-4kgf/cm3,Pv=15×100kPa,Qmax=15m3/h,the corresponding Qmax p1,p2,△pmin is （530、130、400）×100kPa，Qmin=5m3/h,△pmax = 500×100kPa,s=0.2, choose high pressure control valve ,flow characteristics:linear ,with positioner,what diameter(DN) is suitable for the control valve? 1.Flow capacity：Qmax=15m3/h。 2.Pressure difference：△pmin = 400×100kPa,△Pmax=500×100kPa. 3.Kv value calculation: […]

Pnematic control valve working condition and how to choose pneumatic control valve After determining the output force of the actuator, select the corresponding actuator for the control valve according to the requirements of the use environment.Pneumatic control valve should be used when there are explosion-proof requirements on site.Considering from the aspect of energy saving, electric
