Extend the actuator output shaft to bring the end of the shaft
and the coupling together. Rotate the coupling as required
to get a good firm contact between the valve stem and the
output shaft.
Adjust and tighten locking nut(s) if fitted on valve stem side of
the coupling. Ensure that the actuator is centrally aligned with
the valve stem.
If the actuator output shaft reaches its fully extended position
it will be necessary to retract the actuator shaft a sufficient
distance to allow adjustment of the coupling to ensure a tight
shut off in thrust seating valves.
wARnIng
It is critical that there is correct alignment between
actuator output shaft and the valve stem.
note: Mis-alignment will result in increased mechanical
wear and possible damage to the valve stem.
CML-100 & CML-250 units only
Tighten the locking ring fully to secure the actuator in
position. Push and turn the manual override to verify correct
operation of the valve.
CML-750 units
Tighten the four fixings fully.
