How to specify valves and positioners that don't compromise control

Nov. 4, 2015
There have been great achievements in the area of actuators, positioners and control valves, but in some ways we're regressing. There are still many points of confusion, aggravated by the fact that valve positioners may be lying to us, and valve specifications may be misleading.

In this white paper by Gregory McMillan and Pierce Wu, we provide an extensive tour of the sources of poor valve response and the fundamental solutions needed to address the root causes. Temporary fixes are also described to mitigate the consequences until the true solutions can be implemented.
