Adjusting the mechanical stroke limiter
You can adjust the lowest stem position using the
optional stroke limiter (8) on the spindle. This
ensures that an adjustable minimum quantity of
medium continually flows through the equipment.
The optional stroke limiter is only available for
equipment with a rotary actuator. For equipment
with a pneumatic diaphragm actuator, you can
adjust the stem stroke via a handwheel on the
actuator.
 LIft the stem until the desired minimum stem lift
is reached.
 Loosen the spring pin (32).

Turn the adjustment nut (33) downwards until it
hits the stop.

Re-insert the spring pin (7).
