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.
