About the Trabon progressive lubrication components

A divider valve assembly is an inlet section, valve sections and an end section held together by tie rods. While lubricant is supplied under pressure to the inlet the valve pistons cycle progressively; if flow stops the pistons stop and resume at the same point in the cycle. Graco lists uses such as: Metering oil or grease to multiple lube points from a single pump in an automatic lubrication system; Machinery lubrication with Trabon Series-Flo divider valves driven by a Lubemaster pump. Trabon divider valve assemblies dispense lubricant progressively from a single supply. If lubricant flow stops, the divider valve pistons stop and resume at the same point in the cycle when flow returns. Divider valve sections are stamped with the valve style, the discharge per stroke, and the number of outlets.
