This is a spool-type flow divider/combiner valve, it can be used as a pressure-compensated device to split flow in one direction and combine flow in the opposite direction. The valve will divide inlet flow from port 3 to port 2 and port 4. Regardless of system operating pressure conditions, it will combine reduced inlet flow from both port 2 and port 4 to port 3. It will keep a flow to both combining ports when ports 2 or 4 is “free-wheeling”. This function keeps parallel hydraulic-motor drive circuits from stalling in the combining mode.
