Gear splitter is a reversible hydraulic component used for diverting or collecting fluids. The gear splitter adopts a floating side plate, partitioned pressure balance, secondary sealing and other structures. Compared with the throttling type splitter valve, the gear splitter has the advantages of small flow loss, high efficiency, less leakage, and good integration performance. The gear splitter is widely used in hydraulic systems of walking machinery and industrial equipment such as excavators, telescopic cranes, hoists, drilling machines, and steel mills.
