Hi List:
I happen to be in a customer plant yesterday.
The customer have 3 servo controlled valves.
Most of them manufactured by Siemens circa 1969.
Now he wants us to modernize this system using PLCs.
But I do not have the faintest idea on how a servo valve works.
The customers do not have technical manuals on it either.
Could somebody help me explaining in simple terms how can I control a servo valve. The information I could gather from the last valve I saw (the most modern one) was: Torque operation: 2.4 mKp
(???) Turns/cycle: 12.5 (sounds like they have a feedback via encoder?) Revolutions of output shaft: 22 rpm Max thrust for stem nut type A ???? kg (not legible) Motor AEG, 220 Vac, 2700 rpm,
200 watts
Thanks
