Section 5: Mechanical Stroke Adjustment
This section explains:
•
What the mechanical stroke adjustment is.
•
What the factory settings are.
•
How to adjust the travel stops.
A210-211-212-213 Series actuator sizes 32 to 300 have two stroke adjustment stops for
adjusting accurately the stroke of the actuator/valve assembly in open and closed
position.
The smallest actuator, size 32, have limit stops on end-caps.
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.
