Series 04 Gear Operator Mounting
and Lubrication Instructions
For heavy-duty on-off and throttling service of
2” – 48” (51-1219 mm) Quarter Turn Valves.
The Series 04 gear operator is self lubricated for
smooth trouble-free operation. The rugged cast
iron body with o-ring body seals is weatherproof
to IP65. A self locking worm and worm gear drive
holds the valve in the desired position. Features
include a readily accessible hand-wheel, a valve
position indicator and mechanical travel stops
which permit field adjustment of valve position
to specific degrees of rotation.
WARNING
Gear operator handwheel is attached to manual
override shaft with a split spring pin. The pin is
designed to shear if excessive force is applied
to handwheel before internal gears or hous-
ing is damaged. Gear operator with or without
valve should never be lifted by handwheel.
The gear operator is mounted to the valve
as follows:
Manually operate the gear operator until the •
output shaft is in line with the valve stem. On
valve sizes through 12” (305 mm) the valve
stem will be aligned with the “double-D”
stem. On valves larger than 12” (305 mm) the
gear operator and valve stem alignment will
be with the keyway on the full diameter stem.
Place the correct stem adaptor, if required, •
onto the valve stem. It is recommended that a
small amount of grease is applied to the adap-
tor for easier assembly to the valve stem and
gear operator drive shaft.
Install the mounting studs into the gear unit •
base mounting holes. The shorter threaded
end fits into the gear unit base.
CAUTION
Care must be taken not to jam fingers or hand
between gear operator and valve.
Mount the gear unit onto the valve stem. Make •
certain that the mounting studs are correctly
aligned with the holes on the top plate of the
valve or the valve mounting bracket. It may be
necessary to rotate the gear operator hand-wheel
to align the studs with the mounting holes.
Lower the gear operator onto the valve and •
secure in place by fitting the lock washers
and hex nuts.
