The SUN CBDA-LHN is a high-performance, pilot-assisted counterbalance valve with a balanced poppet design. It is primarily used to control overrunning loads by restricting fluid flow from an actuator (port 1) while allowing free flow in the opposite direction (from port 2 to port 1). The pilot-assisted feature allows for smooth and controlled motion, as pressure at the pilot port (port 3) reduces the valve’s setting. Its balanced construction ensures that the valve’s setting is minimally affected by back-pressure at port 2. This cartridge valve is designed for insertion into a T-11A cavity and is ideal for load-holding, safety, and thermal relief applications in mobile and industrial hydraulic systems.
