Setup
312497G 3
Setup
The divider valve is shipped ready to install in your sys-
tem. It has been factory-tested and should not require
any additional modification.
To install the divider valve in your system:
1. Determine an appropriate, remote mounting loca-
tion.
2. Install a rupture to atmosphere fitting with a blow-out
disk that is rated for 7,500 psi or less between the
force feed lubricator pump and master divider valve
inlet.
3. Install an analog pressure gauge at the inlet to the
divider valve.
4. Install a slow or no cycle shutdown in one of the pis-
ton enclosure plugs. Program it to shut down after
no more than 180 seconds without a complete
cycle.
5. Torque. See Table 4 on page 15.
As long as lubricant is supplied under pressure to the
inlet section of the divider assembly, valves sections will
continue to operate in a progressive manner. Divider
assemblies always follow a constant discharge pattern.
Whenever lubricant flow ceases, the valving pistons will
stop. When flow resumes, it will start again at the same
point in the discharge cycle.
Component Identification
Table 3: Typical Divider Valve
Combinations
Divider Valves
A Series-Flo type divider valve is a manifold proportion-
ing device consisting of an inlet and end section plus a
minimum of three valve sections. The divider valve is
manifolded together with tie rods and nuts. A master
divider valve is the first divider valve downstream from
the lube pump. A secondary divider valve is any divider
valve receiving lubricant from the master divider valve.
NOTICE
Do not install a divider valve into a system rated for
more than the valve’s maximum operating pressure.
This type of installation could result in o-ring damage
and cause the divider valve to leak.

Valve Sections (MSP, MHH and MXP
modular-type, divider valves, only)
Valve sections (three or more required per manifold)
contain a piston specially fitted to that section, built in
outlet check valves and various passageways that,
working with the piston, meters and valves the flow of
lubricant (FIG. 2).
Valve sections may be manufactured to require one or
two lube outlets. Stamping located on the face of each
section indicates:
• the style of divider valve section, i.e., MSP, MX,
etc.,
• the discharge per piston stroke expressed in
thousandths of cubic inches (35 = .035 in3 )
and,
• the number of lube outlets required (S = single,
one outlet only; T = twin, two lube outlets
required).
Prefilling Lubricant Distributor Lines
Follow the following procedure exactly as written, in the
order written.
Filling Secondary-to-Lube Point Lines
Refer to FIG. 3. when performing this procedure
.
1. Remove port plugs or performance indicators from
all of the indicator ports on front of secondary
divider valves.
2. Connect a hand pump filled with clean, filtered lubri-
cant to the indicator port closest to the first line to be
filled that corresponds to the output port that is feed-
ing the line to be filled.

NOTICE
• The initial startup and operation is the most critical
operating period for a newly installed machine in
terms of potential for being damaged by unre-
moved/unfiltered lubricant contaminants and lack of
adequate lubrication. Proper prefilling of lubrication
system ensures that lubricant is immediately avail-
able to every lube point during machine startup,
protecting them from damage.
• Use only clean oil filtered to the SAE -recom-
mended cleanliness level of ISO 18/14 (ISO Stan-
dard 4406) when prefilling a system. The
manufacturers of the machine tool and its compo-
nent bearings should be consulted to ensure that
the ISO 18/14 cleanliness level is adequate.

cant to the indicator port closest to the lube output
port that is feeding the line to the secondary divider
valve.
3. Stroke the hand pump to fill the line between the
master divider valve and secondary divider valve.
4. Continue to stroke the pump until the lubricant
purges all the air out of the internal passages of the
secondary divider valve and lubricant flows freely
from all indicator ports with no evidence of included
air.
5. Reinstall the port plugs or performance indicators in
their respective positions in the secondary divider
valve. Do not replace the port plugs or performance
indicators in the master divider valve yet.
6. Repeat Steps 1-5 for each of the other lube lines
between the master divider valve and all other sec-
ondary divider valves.

necessary.
Purging Air From the System
Before machine operation is resumed following mainte-
nance or repair, manual system air purging must be per-
formed.
There are several air purging procedures available
depending upon the maintenance or repair procedure.
NOTE: Use only clean oil filtered to the SAE -recom-
mended cleanliness level of ISO 18/14 (ISO Standard

Steps 1-6, refer to FIG. 6.
1. Install the line from the secondary divider valve to
the lube point, but do not completely tighten the
connection at the lube point.
2. Remove the performance indicator port plug or the
performance indicator from the working valve sec-
tion on the secondary divider valve assembly corre-
sponding to the outlet port and the line connected to
the lube point.
3. Attach a hand pump filled with clean, filtered lubri-
cant to the port on the secondary divider valve that
was opened in Step 2.
4. Operate the hand pump until air-free lubricant is
observed flowing from the line at the lubrication
point.
5. Tighten the fitting at the lubrication point while lubri-
cant is still flowing.
6. Remove the hand pump and reinstall the perfor-
mance indicator or indicator port plug removed in

Locating and Repairing
Blockages
Blocks will cause a higher than normal pumping pres-
sure. Depending on the application or system design,
this blockage will usually result in a complete loss of
lubricant flow into the total system and no bearing will be
receiving lubrication.
The loss of flow due to a blockage is first indicated with
the higher than normal system pressure that is devel-
oped by the pump as it attempts to overcome this block-
age. Higher pressure is limited, isolated and signaled
through the use of various performance indicators, reset
and relief, incorporated into the system design.
Performance Indicators
Performance indicators are pressure-sensitive devices
that pinpoint excessive pressure in the lubricating sys-
tem.
These devices are installed in the indicator ports of
divider valves, signal a fault either by causing an indica-
tor pin to protrude or by releasing lubricant into the
atmosphere.
NOTE: Never block a lube outlet that is designed to dis-
charge lubricant.
Reset Indicator with Memory
Reset indicators stop lube system operation when a
fault occurs. These devices can be used in either master
or secondary divider valves.
When a lube line becomes blocked, the resultant high
pressure pushes the indicator pin through the opening in
the cap. The high pressure prevents the affected divider
valve piston from completing its cycle, causing a pres-
sure backup through the divider valve which trips a pres-
sure switch upstream from the valve and shuts off the
pump.
The indicator pin remains extended until it is reset man-
ually. This helps locate the lube line that is blocked.
Rupture Indicator
Rupture indicators are used on MSP/MH divider valve
applications where lube system pressure exceed 2500
psi. The high pressure from the lube line blockage
causes a disc to rupture. The lubricant then forces an
indicator to protrude, locating the blockage. The high
pressure backs up through the system and trips a switch
to shut the system off. When the fault is corrected, the
disc must be replaced and the pin reset manually.
Automatic Relief Indicator
An automatic relief indicator pinpoints lube line blockage
but allows the lube system to continue supplying lubri-
cant to points that are not blocked. They are used pri-
marily in secondary divider valves. The excessive
pressure created by line blockage moves a piston,
enabling the lubricant to escape through a vent. When
the pressure is relieved, the spring resets the piston.
Because these devices permit the lube system to keep
operating when a lube point is blocked, a separate pres-
sure switch connected to an audible alarm should be
used to warn of high pressure.
Locating and Repairing Blockages
1. Make a visual inspection of the system. Check for
crushed lines or improper divider valve installation.
2. Verify that each divider valve outlet required to dis-
charge lubricant can do so and that no pipe plugs
have been installed in an outlet designed to serve a
bearing or another divider valve.
3. Use a manual pump with a gauge. Fill the pump with
clean, filtered lubricant. Connect the manual pump
to the inlet of the master divider valve and slowly
operate pump. If system will not cycle freely, below
1500 psi, see Master Divider Valve Equipped with
Performance Indicator [Step 4a (below)].
NOTE: Use only clean oil filtered to the SAE -recom-
mended cleanliness level of ISO 18/14 (ISO Standard
4406) when prefilling a system. The manufacturers of
the machine tool and its component bearings should be
consulted to ensure that the ISO 18/14 cleanliness level
is adequate.

4a. Master Divider Valve Equipped With Performance
Indicator
With manual pump connected to the master divider
valve as outlined in Locating Blockages, Step 3,
raise pressure to 2000 psi. The indicators in the
indicator ports will signal the location of the block-
age. An indicator in the up position indicates pres-
sure is in that outgoing line and signals the blockage
is in the area being served from this outlet (FIG. 11).
If no indicator pins are protruding, the blockage is in
the master divider valve.
4b. Master Divider Valve Equipped Without Performance
Indicator
1) With manual pump connected to the master
divider valve as outlined in Locating Blockages,
Step 3, raise pressure to 2000 psi.
2) Remove, one at a time, each indicator port plug
and attempt to operate manual pump after each
plug is removed. Do not exceed 2000 psi.
3) If pressure drops and the master cycles freely
after an indicator port plug is removed, then
blockage is downstream in the area that is being
served from that outlet. See Locating Block-
ages, Step 3.
NOTE:
• If all indicator port plugs are removed, the master
will not cycle. Blockage is in this divider valve.
• When indicator port plug of a blocked area is
removed, a small shot of trapped lubricant will usu-
ally surge out of this outlet as the inlet pressure on
the divider valve drops.
• If testing (Step 4) indicates a blockage in the master
divider valve, this divider valve must be disassem-
bled and cleaned. See Clean Divider Valve, Step 7,
page 15.
5. If in Step 4, a blockage has been indicated
downstream of the master divider valve, install a
manual pump in the indicator port of the master
divider valve that is common to the blocked area.
(See FIG. 12).
a. Proceed to downstream secondary divider valve
and remove all indicator port plugs.
b. Slowly operate manual pump. If lubricant can be
discharged freely through each of the indicator
ports of this divider valve, the blockage is not in
the supply line or the divider valve. Go to step 6.
If lubricant is not freely discharged through
open indicator ports of the second divider valve,
the blockage is in this divider valve or its supply
line. Disconnect supply line at secondary inlet

step 7.
6. Install manual pump into each indicator port of sec-
ondary divider valve in turn and slowly operate
pump (FIG. 13). If high pressure exists, blockage
has been located. Look for crushed line, tight
bearing, improperly drilled fittings and/or lube
inlet port. Correct as necessary.
7. Clean Divider Valve
NOTE: Dirt and foreign material will damage lubricating
equipment. Perform all service and disassembly under
the cleanest possible conditions.
a. Before disassembling any divider valve, make a
sketch noting the arrangement of Valve Sec-
tions. For example: INLET 10T - 20S - 10T -
30S - END (FIG. 14). Also remove end plugs
only and try to move each piston back and forth
without removing the piston from the valve sec-
tion.
b. If all pistons move freely and there is no indica-
tion of a more serious problem, replace end
plugs.
c. Using a new gasket, tighten and torque as indi-
cated in Table 1 (page 11).

d. Clean sections and pistons in suitable clean sol-
vent until all lubricant has been removed.
e. Use compressed air to dry and blow out all
ports thoroughly.
A small metal probe should be used to make
sure all passages are clean and open.
Inspect cylinder bore and piston carefully for
scratches, score marks or other damage.
NOTE: If either piston or cylinder bore is damaged, a
new section must be installed. All pistons are selectively
fitted to the bore for proper clearance. Be sure to rein-
stall piston only into the valve section from which it was
removed.
f. If divider valve section and piston both appear in
good condition, reassemble section making cer-
tain piston slides smoothly but snugly in cylinder
bore.
g. Repeat cleaning and inspection of each section.
After all sections have been cleaned, blown out,
inspected and found to be in good condition,
reassemble divider valve using notes and
sketches (Step 7) as a reference.
NOTE:
• Always use new gaskets.
• Test operation of divider valve using manual pump.
Contamination Blockage
If dirt, foreign material or any other form of contamina-
tion is found in a divider valve, cleaning that divider valve
will only temporarily solve contamination blockage prob-
lems. The source of the contamination must be elimi-
nated for satisfactory service.
The system filtering method must be investigated, filter
elements should be inspected and cleaned if necessary.
The reservoir filling method should be reviewed to elimi-
nate any chance of foreign material entering the reser-
voir during filling.
Separation Blockage
If a hard wax or soap-like material is found in the Valve
Section, grease separation is occurring. This means that
the oil is being squeezed from the grease at normal sys-
tem operating pressure and the grease thickener is
being deposited in the divider valve. Cleaning the divider
valve will only temporarily solve the problem. Consult
your lubricant supplier for recommendations on alter-
nate lubricants and your local Graco/Trabon distributor
to verify compatibility with centralized lubricating sys-
tems.
If all indictor port plugs are removed, master will not
cycle. Blockage is in this divider valve.(FIG. 11).

Performance Indicators
Performance indicators are pressure sensitive devices that signals a fault when there is excessive build up of pres-
sure in a series progressive lubricating system. A fault is identified by either causing a pin to protrude or by releasing
lubricant to the atmosphere.
Reset Indicator with Memory
Reset Indicators stop lube system operation when a fault occurs. They can be used in either master or secondary
divider valves. Fault is indicated when a pin protrudes through the opening in the cap and is manually reset.

Automatic Relief Indicator
Automatic Relief Indicators pinpoint lube line blockage but allow the lube system to continue to supply lubrication to
points that are not blocked. They are used primarily in secondary divider valves. When needed, pressure is relieved
through a vent. When pressure is relieved the spring resets the piston. Because these indicators permit the lube sys-
tem to continue operating when a lube point is blocked, a separate pressure switch connected to an audible or visual
alarm should be used to warn of high pressure.
Rupture Indicator - MH Divider Valves Only
Rupture Indicators are only used on MH divider valve applications where lube system pressures exceed 2500 psi.
The high pressure from a lube line blockage causes a disc to rupture. The lubricant then forces an indicator pin to
protrude, locating the blockage. The high pressure backs up through the system and trips a switch to shut the system
off. When the fault is corrected, the disc must be replaced the pin reset manually.

Rupture-to-Atmosphere Indicator
Rupture-to-Atmosphere Indicators are standard on all Graco pumps. When the pressure reaches a predetermined
pressure setting, the pressure disc ruptures, venting lubricant into the atmosphere and relieving pressure.
Rupture-to-Atmosphere Indicator with Spud Assembly
A Spud Assembly is available to return vented lubricant to the reservoir by way of a tube. A high pressure switch is
recommended to provide an audible or visual warning alarm that height system pressure has occurred.

Singling and Crossporting Bar Assemblies
Singling Kits externally convert a “T” (Twin Outlet) section to an “S” (Single Outlet) section.
Crossporting Kits externally combine the output of two (2) adjacent sections.
Cycle Indicators
Cycle Indicators provide a means of visually monitoring lube flow thru the system.
The pin type cycles in and out when lubricant is flowing. Movement of the pin is caused by the piston (the two are
attached) so that when the piston moves the indicator pin in and out once, the entire divider valve has cycled.

Cycle Counters - Part No.: 563444
The purpose of a cycle counter is to give assurance that the lubricant is flowing thru the system. Every “count” indi-
cates one complete cycle of the divider valve. Visual inspection and/or recording of counts provides a constant check
on the performance of your lubricant system and the pump. The Cycle Counter can be used on any MJ, MS, MH, MX
and MXP divider valve assembly.
Cycle Switches
The function of a Cycle Switch is to electrically give assurance that the lubricant is flowing through the system. Actu-
ated by a cycle pin, the switch can be wired to various controls.
NOTE: The cycle switch MUST be attached to a section that is equipped with a cycle indicator pin.

Proximity Cycle Switches
The Proximity Cycle Switches are magnetically operated single throw switches that sense the movement of the
divider valve piston when it is cycling. Each proximity cycle switch provides a signal that is used to monitor the sys-
tem. There are 3 different types of switches available.
Reed Type Proximity Switch: Can be used with oil applications only for MS, MH and MGO divider valves at pres-
sures up to 518 bar (7500 psi) at cycle rates under 60 cycles per minute.
Field Sensitive Magnetic Proximity Switch: Dry contact, ceramic magnet operated switch. Used at pressures that
do not exceed 242 bar (3500 psi) at cycle rates up to 200 cycles per minute. Used in MS/MH, MX/MXP and MGO
divider valves. An explosion proof version for MS/MH divider valves is available.
Magnetic Operated Proximity Switch: Not limited to valve size. Miniature snap-action switch is tripped by attraction
of internal magnet to the moving divider piston. Can be used at pressures up to 518 bar (7500 psi) at cycle rates that
do not exceed 150 cycles per minute.
