Pressure Relief Procedure
Follow the Pressure Relief Procedure whenever
you see this symbol.
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.
To install the divider valve in your system:
This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury
from pressurized fluid, such as skin injection,
splashing fluid and moving parts, follow the Pressure
Relief Procedure when you stop spraying and before
cleaning, checking, or servicing the equipment.
1. Determine an appropriate, remote mounting location.
2. Install a rupture to atmosphere fitting with a blow-out
disk that is rated for 7,500 psi (52 MPa, 517 bar) 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.
1. Verify pump feeding valve is stopped and disconnected from, or locked out of it’s driver.
2. Using a wrench, slowly loosen inlet nut.
3. Then, using a wrench, slowly loosen each port nut.
4. Install a slow or no cycle shutdown in one of the piston 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.
Setup
The divider valve is shipped ready to install in your system. It has been factory-tested and should not require
any additional modification.
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.
For MJ and MX series valves only: Gaskets (a) must be
installed between every valve section (b) of the block
assembly to prevent leaking.

A Series-Flo type divider valve is a manifold proportioning 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.
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,

NOTICE
•
•
3. In order to verify when lubricant is flowing and has
reached the end of the lube line, loosen the connector at the lube point of the line that is to be filled.
The initial startup and operation is the most critical
operating period for a newly installed machine in
terms of potential for being damaged by unremoved/unfiltered lubricant contaminants and lack of
adequate lubrication. Proper prefilling of lubrication
system ensures that lubricant is immediately available to every lube point during machine startup,
protecting them from damage.
Use only clean oil filtered to the SAE -recommended 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.
5. Tighten the lube line connector at the lube point, but
do not replace the port plugs or performance indicators into the ports on the front of the working section.
6. Repeat steps 1-5 for each of the other lube lines
connected to the other outlet ports in the secondary
divider valve assembly and for any other secondary
divider assemblies in the system.
NOTE: Do not replace any of the performance indicators or port plugs removed in Step 1 until the line-filling
procedure described in Section 2 (Filling Master

Locating and Repairing
Blockages
Blocks will cause a higher than normal pumping pressure. 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 developed by the pump as it attempts to overcome this blockage. 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 system.
These devices are installed in the indicator ports of
divider valves, signal a fault either by causing an indicator pin to protrude or by releasing lubricant into the
atmosphere.
NOTE: Never block a lube outlet that is designed to discharge 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 pressure backup through the divider valve which trips a pressure switch upstream from the valve and shuts off the
pump.
The indicator pin remains extended until it is reset manually. This helps locate the lube line that is blocked.
312497P
Rupture Indicator
Rupture indicators are used on MSP/MH divider valve
applications where lube system pressure exceed 2500
psi (17 MPa, 172 bar). 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 lubricant to points that are not blocked. They are used primarily 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 pressure 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 discharge 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 -recommended 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.

Repair
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 (14 MPa, 138 bar). The
indicators in the indicator ports will signal the location of the blockage. An indicator in the up position
indicates pressure is in that outgoing line and signals the blockage is in the area being served from
this outlet (FIG. 12).
If no indicator pins are protruding, the blockage is in
the master divider valve.
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 usually 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 disassembled and cleaned. See Clean Divider Valve, Step 7,
page 15.

d. Clean sections and pistons in suitable clean solvent 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 reinstall piston only into the valve section from which it was
removed.
f.
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 system 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
alternate lubricants and your local Graco/Trabon distributor to verify compatibility with centralized lubricating
systems.
If all indictor port plugs are removed, master will not
cycle. Blockage is in this divider valve.(FIG. 12).
If divider valve section and piston both appear
in good condition, reassemble section making
certain 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 contamination is found in a divider valve, cleaning that divider
valve will only temporarily solve contamination blockage
problems. The source of the contamination must be
eliminated 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 eliminate any chance of foreign material entering the reservoir during filling.

Performance Indicators
Performance indicators are pressure sensitive devices that signals a fault when there is excessive build up of pressure 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 system 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.

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” indicates 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. Actuated 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 system. 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 pressures up to 518 bar (7500 psi, 52 MPa) 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, 24 MPa) 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.
