Position the disc in the closed position.
Install the ratchet plate using socket head cap screws and
lockwashers, but do not tighten the fasteners.
Install the drive key in the shaft. Tap the key into place to
ensure it is fully seated in the keyway .
Install the handle so that it is parallel with the disc face.
The locking lever must be fully retracted before it will pass
through the ratchet plate. Tighten the set screw in the
handle against the key.
With the handle installed flush with the ratchet plate,
engage the locking lever with the ratchet plate. Using the
handle, adjust the position of the ratchet plate until the disc
face is parallel with the valve face, then tighten the
fasteners securely.
Remove the handle by disengaging the locking lever and
lifting up. The locking lever will slide thru the ratchet plate
only in the disengaged position.
Remove the ratchet plate fasteners and rotate the plate
180°. Reinstall the fasteners but do not tighten them.
Reinstall the handle 180° from the standard position so
that it is parallel with the disc (Note: The locking lever must
be disengaged). Tighten the handle set screw against the
key.
Adjust the ratchet plate as described above.
Line up the shaft flat to permit the insertion of the wedge
pins. Install the first wedge pin in the disc hole closest to
the top of the valve. Finger tight installation is appropriate.
Move the shaft fully into the valve and against this first
installed pin. Insert the second pin. Tap both wedge pins
in equal amounts until all play between shaft and disc is
removed. Care should be taken not to attempt to over seat
the wedge pins. If the pin is flush or protruding after tapping
in, tack weld on the opposite side for security. Otherwise,
peening of the installing side is recommended.
Install a new end seal if applicable with the end cap as
described in Steps 4 through 7 of the End Cap Seal
Replacement procedure.
Install new packing box components as described in
Steps 4 through 10 of the Packing Replacement
procedure.
Install new seat as described in the Seat Replacement
procedure.
Cycle the valve several times to ensure the disc is pinned
tightly to the shaft and there is no shaft binding or seat
damage before reinstalling the valve in the pipeline.
Reinstall the actuator mounting hardware and actuator.
Set the actuator stops.

MAINTENANCE INSTRUCTIONS
Position the disc in the closed position.
Install the actuator mounting bracket on the valve body
with the actuator mounting holes facing up-ward. Fasten
the bracket securely in place with the appropriate ma-
chine bolts and lockwashers.
Install the drive key in the keyway of the shaft. Tap the key
in place to insure it is fully seated.
Install the drive coupling on the shaft by lining up the
proper keyway in the coupling with the key in the shaft.
Rotate the actuator shaft to the full clockwise position.
Align the drive coupling with the actuator shaft and install
the actuator on the mounting bracket.
Fasten the actuator to the mounting bracket with the
appropriate machine bolts and lockwashers. It may be
necessary to slightly rotate the actuator shaft to align the
mounting holes in the actuator with the mounting bracket.

Install the drive key in the shaft. Tap the key into place to
ensure it is fully seated.
Rotate the gear shaft to the full clockwise position. Align
the keyway in the gearbox bore with the key in the shaft
and slide the gearbox onto the shaft.
Fasten the gearbox to the mounting bracket with the
appropriate machine bolts and lockwashers. It may be
necessary to rotate the gear shaft slightly to align the
mounting holes in the gear with the plate.
Adjust the stops in the gearbox to position the face of the
disc parallel with the face of the valve in the closed
position and perpendicular to the face of the valve in the
open position.
