Description
These preset metered valves are designed to
dispense preset quantities of fluid lubricants.
Each model is equipped with an inlet swivel, a
high-volume manual nozzle, and rigid extension.
The models differ in the units of measure that
are metered and the face dial range. See Table 1
for details.
A totalizer keeps a lifetime record of the
amount dispensed in a unit of measure labeled on
the dial.
These models are also equipped with an
internal filter screen to prevent damaging
contaminants from entering the meter.
Operation
Turn the pointer counterclockwise to the
required quantity of fluid to be dispensed. To
dispense, depress the lever until it locks.
The lever disengages automatically once the
preset amount is delivered.
Emergency Release Mechanism
To stop a preset delivery before completion,
move the lock pawl to the right. See Figure 1.
This releases the lever and stops delivery. CAUTION
Do not turn the pointer clockwise. Damage can occur.

Revision (10-04) 4 Alemite Corporation
Overhaul
Prior to performing any maintenance procedure, the
following safety precautions must be observed. Personal
injury may occur.
WARNING
Do not use halogenated hydrocarbon
solvents such as methylene chloride or 1,1,1-
trichloroethane in this valve. An explosion can
result when aluminum and/or zinc-plated parts in
the valve come in contact with halogenated
hydrocarbon solvents.
Release all pressure within the system prior to
performing any overhaul procedure.
• Disconnect the air supply line from the
pump motor.
• Into an appropriate container, operate the
control valve to discharge remaining
pressure within the system.
Never point a control valve at any portion of your
body or another person. Accidental discharge of
pressure and/or material can result in injury.
Read each step of the instructions carefully.
Make sure a proper understanding is achieved
before proceeding.
