L10103MHH Modular Divider Valves

MHH divider valves precisely proportion a volume of oil to satisfy
the different requirements of every point in a lube system. They
operate in sequential fashion to ensure that no point is missed.
Series-Progressive design provides ready monitoring capability.

MHH divider valves are available for use with petroleum or
synthetic oils and at pressures up to 7500 PSI. The modular,
stackable sub-plate design provides maximum application
flexibility. Accessory components are available for visual
diagnostics and electrical monitoring.

FEATURES/BENEFITS

• Use in terminating oil systems at pressures up to 7500
PSI (517 bar)

• Lubricate up to 16 points from one divider valve
assembly.

• Soft-seal O-ring construction and indicator ports
minimize leakage and reduce maintenance.

• Built-in check valves prevent lube back flow and help
keep lube lines full.

• Stackable sub-plate design simplifies build-up,
installation and maintenance.

DESCRIPTION

Each MHH divider valve assembly incorporates from three to
eight working piston sections (1), associated sub-plate sections
which include the outlet distribution ports (2), an inlet section
(3), and an end section (4).

“Twin” sections are ported to provide separate outputs from
each end of a working piston and direct them to two lube points.
“Single” sections are ported to combine the outputs from each
end of a working piston and direct it to one lube point.

Cross port plates (5) may be installed between working piston
sections and sub-plate sections to combine the outputs of
successive working piston sections. (Cross port plates must
not be installed beneath bottom working sections.) Singling
plates (6) may be installed to combine the outputs from both
ends of a working piston in any "Twin" section. Bypass sections
(not shown) may be used in place of working piston sections to
eliminate inactive lube lines without disturbing active lube lines,
or to provide for future system expansion. (Divider assembly
must contain at least three working sections in addition to
bypass section.)

• Ample clearance between outlet connections for
elbows and 3/8" lube lines.

• Performance indicators, cycle indicators and proximity
switches monitor divider valve action to simplify
troubleshooting and repair.

• Choice of SAE or NPSF inlet and outlet connections

• Choice of 70 Durometer Buna-N or 90 Durometer
fluoroelastomer O-rings.

CYCLE INDICATORS

By sensing divider valve piston movement, lube volume can be
accurately monitored and controlled. A variety of mechanical
and electrical cycle indicators are available for this purpose.

DIVIDER VALVE SECTIONS WITH
ATTACHED CYCLE INDICATOR PIN

18 through 30 size MHH divider valve sections are available
with a factory-installed cycle indicator pin attached to either
end of the piston. The pin moves in and out one time for each
complete cycle of the divider valve assembly. Application
pressure is limited to 3500 PSI.

See Page 3 for part numbers. Consult Graco for part numbers
of sections with pin on left-hand side and for part numbers of
sections with fluoroelastomer seals.

MAGNETIC VISUAL CYCLE
INDICATOR

A No-Weep Magnetic Visual Cycle Indicator can be installed
in place of a piston enclosure plug on any size divider valve
section. Six steel balls in a transparent sleeve follow a magnet
which moves with the cycling piston. Unlike a cycle indicator
pin, working section displacement is not reduced. Suitable for
application at pressures up to 7500 PSI.
Part number 563251 (509-932-522)

UNIVERSAL CYCLE COUNTER - FOR USE WITH
DIVIDER VALVE SECTION HAVING ATTACHED
CYCLE INDICATOR PIN

Switch bracket clamps to a cycle indicator pin housing. Cycle
indicator pin movement repeatedly trips an electrical (limit)
switch. Switch pulses provide input to a system controller
which counts them to control and verify completion of the lube
cycle.

Counter housing clamps to a cycle indicator pin housing. A
6-digit mechanical counter, advanced by the movement of a
divider valve cycle indicator pin, provides visual assurance that
the system is functioning. Every “count” indicates one complete
cycle of the divider valve assembly. Suitable for application at
pressures up to 3500 PSI.

PERFORMANCE INDICATORS

Performance indicators respond to the increase in pressure
which occurs when lube lines or lube points become blocked.
When installed in indicator ports of working piston sections, they
pinpoint blockage location. Some models relieve the excessive
pressure, allowing the divider valve to continue to cycle. Some
models do not relieve the excessive pressure, causing the
divider valve to lock up.

Automatic Reset Relief Indicator

A spring-loaded piston unseats when lube line blockage occurs
and lubricant escapes through a vent to the atmosphere. This
allows the system to continue lubricating the other unaffected
points. When the blockage is cleared, the piston automatically
reseats.

3,000 psi (207 bar) 563176 508-310-475

Disc-Type Pressure Indicator

A blow-out disc ruptures when lube line blockage occurs and
lubricant forces a pin to protrude from the body of the indicator.
There is no provision for relief and the pressure escalates until
relieved elsewhere in the system. The disc must be replaced
and the pin reset manually after the blockage is eliminated.

Spring-Type Pressure Indicator with Memory

When blockage occurs, a spring-loaded piston unseats and
forces a separate indicator pin to protrude from the body of
the indicator. There is no provision for relief, and the pressure
escalates until relieved elsewhere in the system. The spring
automatically reseats the piston but the indicator pin must be
reset manually after the blockage is eliminated.
