Lower and upper limit of the valve operating area (MIN, MAX)
With the parameters MIN and MAX, the lower and upper valve position (physical stroke) of the valve
operating area can be established – independent of the character of the setpoint characteristic curve.
The characteristic curve is completely adjusted corresponding to the established lower and upper valve
position. The following figure shows as an example the influence of the parameters on the linear set
point value characteristic curve with the setting MIN 20 % and MAX 80 %.

Influence of the parameters MIN and MAX on the setpoint characteristics curve – example
Typically, the smallest physical stroke is assigned to the smallest setpoint value and the largest
physical stroke to the largest setpoint value – dependent on the configuration and parameterisation
