Stroke 30mm
Stroke 70mm
Installation position of connection bar for valve stroke
Note
After installation, operate valve from 0 stroke to 100% stroke with using air filter regulator
on the actuator. When the stroke is both 0% and 100%, feedback lever should not be
reached to the lever stopper on the backside of YT-2300. If feedback lever reaches to
the lever stopper, move attachment position of YT-2300L to the direction becoming more
distant from yoke center.
Check whether or not lever stopper and feedback lever is contacted
9. If YT-2300L is installed accurately as above procedures, lock the bolts and nuts of
