Mechanical Stroke Adjustment

Section 5: Mechanical Stroke Adjustment

This section explains:

•

What mechanical stroke adjustment is.

•

What the factory settings are.

•

How to adjust the travel stops.

Bettis Q-Series actuator sizes 40 to 1600 have two stroke adjustment stops for adjusting
accurately the stroke of the actuator/valve assembly in open and closed position.

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.
