6.5.1 Replacing the set point
springs
Type 2371-11 · Set point springs
You need to replace the set point springs (7)
with both plates to achieve a different set
point range. We recommend changing the
entire actuator housing (8) with set point
springs (7) and set point screw (6).
How to proceed:
The regulator does not need to be removed
from the pipeline.
See section 6.4 on page 21, steps 2 and
3.
