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.

Divider Valves
A Series-Flo type divider valve is a manifold proportion-
ing 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.

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.
