The Sun FDBA-LAN is a high-performance, pilot-assisted counterbalance valve with a balanced poppet. It is designed to control overrunning loads by creating back pressure at port 2, preventing the load from running ahead of the pump. This valve provides excellent stability and low-pressure drop, ensuring smooth and reliable operation in demanding hydraulic circuits. Its screw-in cartridge design allows for easy installation into standard T-11A cavities, making it a versatile solution for load-holding, safety, and motion control applications.
