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 eld adjustment of valve position

to specic 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 ts into the gear unit base.

CAUTION

Care must be taken not to jam ngers 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 tting the lock washers

and hex nuts.
