Lever and pin position
The positioner is adapted to the actuator
and to the rated travel by the lever on the
back of the positioner and the pin inserted
into the lever.
The travel tables on page 15 show the
maximum adjustment range at the position-
er. The travel that can be implemented at the
valve is additionally restricted by the selected
fail-safe position and the required compres-
sion of the actuator springs.
The positioner is equipped with the M lever
(pin position 35) as standard.

ver.

both directions.
