Rajan M. Meet all the criteria
I prefer closed-loop systems since they react better to external problems. However, it also means that I have to select a valve and actuator that is magnetic for a fast positioning time, high resolution, and rangeability. THe MXG461.25-8.OU from Siemens fit all of those criteria - and the results speak for themselves. Accuracy and efficiency is everything that I could ever ask for and I finally achieved it.
