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, nuts, and lock washers.
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 lock washers. It may be
necessary to slightly rotate the actuator shaft to align the
mounting holes in the actuator with the mounting bracket.
Adjust the stops in the actuator to position the face of the
disc parallel with the face of the valve body in the closed
position and perpendicular to the face of the valve body in
the open position.
Position the disc in the closed position.
Install the ratchet plate using machine bolts, nuts and lock
washers, 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.
Position the disc in the closed position.
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 lock washers. 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.
