Trabon® MX Series-Flo Dividers
DESCRIPTION
Trabon MX Series-Flo® Divider Valves are designed for heavy
service and are ideal for large steel mill systems and similar
applications. For modular version (MXP) having the same output
capacities, see bulletin 10132.
A typical MX Series-Flo® Divider Valve Assembly (to the right)
consists of an inlet section, end section and three to ten valve
sections. The basic divider assembly will serve between three and
twenty lube points.
The MX valve sections, which have built-in outlet check valves,
are available in various output per piston cycle sizes (see
specifications). Each twin (T) section has 2 outlets, one from each
side of the section. Each single (S) section has 1 outlet on either
side, but one outlet must be plugged to operate properly. For
applications with continuous oil lubrication (Meter-Flo) the built in
outlet check valves may be removed.
FEATURES/ADVANTAGES
Delivers metered amount of lubricant.•
Economical and compact design.•
Lubricant outlets easily added or removed.•
Simple to install on new or existing machines.•
Built-in outlet check valves.•
Hone-fitted metering pistons.•
OPERATION
Operational sequence of an MX Series-Flo® Divider Valve
Assembly is defined as “progressive”. The term progressive
means that each valve section completes its piston stroke,
discharging a measured amount of lubricant to the bearing it
serves before the following valve section operates. As long as
lubricant is supplied under pressure to the inlet section of the
divider assembly, valve 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.

NOTES:
1. Capacity sections are specified starting from inlet section, and must equal
number of sections specified.
2. When a capacity section is crossported, its outlet is plugged and output is
diverted to the next section, farthest from the inlet.
3. Last capacity section, farthest from the inlet, cannot be crossported.
4. Singled capacity sections can be crossported on one side only.
5. When capacity section is singled, the outlet not being used is plugged.
6. Internal crossporting can be supplied on a capacity section only when
supplied on a manifold assembly (if supplied as a loose unit, it can be field
drilled only).
7. External singling and crossporting bars are available for field installation.
8. Cycle Indicator Pin and Proximity Switch are not available on 0.025 capacity
section.
9. Indicate crossport option after capacity section if required, omit if not
required.
10. Divider systems should be limited to first and second stages only. Third
staging is not recommended. Refer to Trabon bulletins L20101, L20105, and
L20115 for further information on system design.
11. For information on the modular version (MXP) having the same output
capacities refer to Trabon bulletin L10132.
