Setting Mechanical Travel Stops
NOTICE
If the unit came assembled to a valve, the stops have been factory-set and DO NOT
need adjustment.
Mechanical travel stops are designed to prevent over travel while manually operating
the actuator. They are not designed to stop the electric motor.
Mechanical travel stops are located outside of the actuator base for easy
readjustment. Stainless steel lock nuts with O-ring seals hold the travel stops
securely in place. Travel stop spacers are used to ensure that travel stop bolts are
not engaged to where they could limit 0° to 90° electrical operation.
NOTE:
Actuator Size 130, 180 does not use travel stop spacers.
