instruction and operating manual
4.6 Setting of the angular stroke: mechanical stops
It is important for the mechanical stops to end the angular stroke at both extreme valve
positions (fully open and fully closed).
The setting of the angular stroke is performed by adjusting the travel stop screw mounted
on the actuator housing.
For the adjustment of the stop screw proceed as follows:
• Loosen the lock nut.
• Screw 1: open;
To set the mechanical stop in opening, manually bring the actuator to the completely open
position, then turn screw 1 clockwise.
• Screw 2: close.
To set the mechanical stop in closing, manually bring the actuator to the completely close
position, then tighten screw 2.
If the actuator angular stroke is stopped before reaching the end position (fully open or
closed), proceed as follows:
- unscrew the stop screw by turning it anticlockwise until the valve reaches the correct
position;
- when unscrewing the stop screw, keep the lock nut still with a wrench so that the sealing
washer does not withdraw together with the screw;
- tighten the lock nut.
If the actuator angular stroke is stopped beyond the end position (fully open or closed),
proceed as follows:
- screw the stop screw by turning it clockwise until the valve reaches the correct position
- tighten the lock nut.
