Contamination blockage
If dirt, foreign material or any other form of contamination is found in a divider
valve, cleaning will only temporarily solve contamination blockage problems.
The source of the contamination must be eliminated for satisfactory service.
Separation blockage
If a hard wax or soap like material is found in the intermediate section grease
separation is occurring.
This means that the oil is being squeezed from the grease at normal system operating
pressure and the grease thickener is being deposited in the divider valve.
Cleaning the divider valve will usually result in only temporarily solving the
problem.
Consult your lubricant supplier for recommendations on alternate lubricants and
your local Trabon distributor to verify compatibility with centralized lubricating
systems.
