Angular Displacement

Below table identifies, per actuator size, what the angular displacement of the pinions is,
when using the limit stop screws.

NOTICE
In case of air leakage over the limit stop bolts, turn the lock nut of the limit stop bolts
tighter, until leakage stops.
Mechanical Stroke Adjustment
Turn the "closed" stop clockwise to reduce or counterclockwise to increase the
travel. Consult chapter 5.1.3 (angular displacement of the pinion), to define how
far the limit stop must be turned in or out.
Remove air supply. Actuator will move to the closed position.
Check whether the actuator valve assembly is in the required position.
If not repeat steps 1 to 5.
Remove air supply.
For adjusting the open position repeat steps 1 to 6, but now for the open position
and "open" stop (1).
