Hi all,
I have a customer that has managed to order an AUMA valve without positioner. From experience, we do not want to implement a contactor based direction changer (to open-close valve).
Has anyone ever done valve control with a VSD?
The valve is used for controlling temperature, and is expected to move a lot (between 25-100%). It will usually only close when the system is stopped.
