Control valves selection in hydrogenation

[chirag]

In hydrogenation reaction pressure is 30 kg/cm2 and temp is 80C’. (for GAS application)
for control valve selection i have consider MOC(ss136) and CLASS(600).
is there any other specification require to select control valve in hydrogenation?

Try referring to Nelson Curve and figuring out the MOC.
