2. Attach the positioner with the bracket to the actuator yoke
–
DO NOT TIGHTEN THE BRACKET COMPLETELY.
3. Connect connection bar to the actuator clamp. The hole gap on the feedback lever is 6.5mm so
the connection bar
’s outer diameter should be less than 6mm.
4. Connect an air-filter regulator to the actuator temporarily. Supply enough air pressure to the
actuator in order to position the valve stroke at 50% of the total stroke.
