6. Connect supply pressure to the actuator temporarily. Supply enough supply pressure to the
actuator in order to position the actuator clamp at 50% of the total valve stroke.
7. Insert the connection pin of the feedback lever in to the bar slide assembly. The pin should be
inserted when the actuator clamp is at 50% of the total valve stroke.
Correct way to connect feedback lever, connection pin, and lever spring
8. Check if feedback lever is parallel to the ground at 50% of the valve stroke. If it is not parallel,
adjust the bracket or feedback link bar to make parallel. Improper installation may cause poor
linearity and may create unnecessary hunting during the operation.
9. After installing the positioner, operate the valve from 0% to 100% stroke by using direct air to the
actuator (manual position). On both 0% and 100%, the feedback lever should not touch the
lever stopper, which is located on the back of the positioner. If the feedback lever touches the
stopper, the positioner should be installed further away from the yoke.
