Section 5: Mechanical Stroke Adjustment

This section explains:
•
•
•
EL-O-Matic F actuator sizes 25 to 4000 have two stroke adjustment stops for adjusting
accurately the stroke of the actuator/valve assembly in open and closed position.
The smallest actuator, size F12, does not have limit stops.
The factory setting of the stroke is 90°. Most quarter-turn valve applications will not require
readjustment of these settings.
If required the stroke can be adjusted by means of two-stroke adjustment bolts.
