B100 is a non-adjustable proportional divider, it also offers free reverse flow for both outlet ports.
Flow can travel in reverse through both outlet ports and is not metered when it goes in reverse.
The non-metered flow travels past the poppet, down the center of the valve, past the orificed spool and through the inlet.
The two outlet flows are pressure compensating and the sum of said flows equals the inlet flow. The ratio of the outlet flows must be specified when ordering.
