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. Part number 563444 (527-002-410)

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.
Relief Pressure Part No. Old Part No.

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.

6,400 psi (441 bar) 563226 509-499-165
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.
