SETTING THE MECHANICAL STOPS
To set the actuator’s mechanical stops, proceed as follows:
- Loosen the locknuts on both stop screws.
- Rotate both stop screws counter-clockwise two (2) turns.

Open Position: Move the actuator to the full open position. Rotate Stop Screw 1 one (1) turn
clockwise until it bottoms out, then rotate it counter-clockwise ½ turn.
Tighten the locknut by rotating it clockwise.

Closed Position: Move the actuator to the full closed position. Rotate Stop Screw 2 one (1)
turn clockwise until it bottoms out, then rotate it counter-clockwise ½ turn.
Tighten the locknut by rotating it clockwise.
Using the handwheel, check that the travel of the actuator is correct. If the actuator stops before
reaching the end of travel (full open or full closed), proceed as follows:
- Rotate the Stop Screw counter-clockwise (CCW) while holding the locknut in position with a second
wrench. Manually move the actuator until the valve reaches the correct position. Re-tighten the
locknut.
If the actuator travels beyond the full range of valve travel (full open or full closed), proceed as follows:
- Rotate the Stop Screw clockwise (CW) while holding the locknut in position with a second wrench.
Manually move the actuator until the valve reaches the correct position. Re-tighten the locknut.
