Cross-porting (Divider Valve)
Installing a closure plug in one or more outlets may combine outputs from adjacent outlets.
Lubricant from a plugged outlet is redirected to the next adjacent outlet in descending
numerical order. Outlets 1 and 2 must not be plugged since they have no cross-port
passage to the next adjacent outlet.
In figure 5 outlets 5 and 3 are cross-ported and directed through outlet 1. In this example,
outlet 1 will dispense three times as much lubricant as outlet 7. The tube ferrules in outlets 1
and 7 block the cross-port passage so that lubricant flow is directed through the outlets.
