We are in a phase of optimization of plant we are given to check calibration of the valves but when we give 0 to 100% we get correct valve to travel but from 100 to 0 percent the travel goes down by 1.5% and takes very long time to come back to require value. Valve sizes are from 6 inch to 10 inch valves.
How this action be faster so as to minimize the error within 0.5% of the span?
I auto calibrate, I put tuning values but result is same.
