Function Block: Valve Adjustment

This function block is used to compensate for design-related differences between
the magnets and the valve. The goal is to achieve the most linear connection
possible between the process value and the volume flow.

Definition of "Overlap"

There are three types of overlap:
Negative overlap: A defined flow of the respective medium also flows
•
through in the zero position of the valve.

• Zero overlap: The valve has a defined zero position and opens very
quickly.
