L10103MHH Modular Divider Valves
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.
CYCLE INDICATOR SWITCH - 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.
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
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.
