The Sun FDCB HAN is a high-performance, screw-in hydraulic cartridge valve designed for precise flow control. As a pressure-compensated, priority-type flow control valve, it takes an input flow and splits it into a constant, priority flow and a bypass (excess) flow. The key feature of the FDCB HAN is its ability to maintain a constant priority flow rate regardless of variations in load pressure at either the priority or bypass ports, or changes in the input flow. This makes it ideal for applications requiring a stable and reliable flow to a primary hydraulic function, such as steering or motor control, while allowing excess flow to be used for secondary functions. This valve fits into the standard Sun T-11A cavity.
