Divider blocks (also known as distribution blocks or divider valves) provided by CPI precisely distribute correct lubrication, reducing the size of lubricator boxes and maximizing lubrication system efficiency. XD+ divider block assemblies consist of three to eight working sections, one inlet section with integral intermediate, intermediate sections for each working block, and one end section with integral intermediate. A single assembly can feed from one (1) to sixteen (16) lubrication points.
