Looking on the end of the gear operator the right hand bolt is •
the close adjustment. (See Figure 1)
Remove the valve position indicator and view the position of
•
the valve stem. (See Figure 2)
Rotate the close travel stop screw clockwise until the screw
•
touches the quadrant.
We have to consider that in the full closed position the stem
•
“double D” flats align with the position of the valve disc (See
Figure 3) . Similarly on the full diameter stem the keyway po-
sition will align with the valve disc position.
Loosen the lock nut and back off the close travel stop screw
•
one turn in the counter-clockwise direction.
Rotate the hand-wheel until the sides of the “double D” or
•
the sides of the keyway are parallel with the face of the valve.
(See Figure 4)
Verify that the “double D” or keyway is still parallel to the
•
valve face.
Carefully re-tighten the travel stop lock nut
•
Replace the valve position indicator. •
At this point apply a sealant to the lock nut of the close travel •
stop to ensure that it will not be readjusted.
When factory setting the close stop, as the valve is not in line,
•
instead of aligning the shaft with the face of the valve, it is
more accurate to measure from the face of the valve to the
disc face at the 3 o’clock and 9 o’clock positions and adjust
the gear unit until the measurements are equal.
