6. Check if feedback lever is vertical to the valve stem at 50% of the valve stroke. If it is

not vertical, adjust the bracket or the connection bar to make vertical. Improper

installation may cause poor linearity.

Fig. 4-6: Feedback lever and valve stem

7. Check the valve stroke. The stroke numbers are engraved on the feedback lever of the

positioner. Position the connection bar at the number on the feedback lever which

corresponds with the desired valve stroke. To adjust, move the bracket, the connection

bar or both.

※

The effective linear lever angle is 23 degree.

Stroke : 30mm

Stroke : 70mm
