The Sun Hydraulics CBCHLJN is a high-performance, pilot-to-open counterbalance valve designed for controlling overrunning loads in hydraulic systems. This standard capacity cartridge valve allows free flow from the directional valve (port 2) to the load (port 1) while blocking flow in the opposite direction until sufficient pilot pressure is applied at port 3. The CBCHLJN ensures smooth, stable, and safe motion control by preventing load runaway. It features a sealed, tamper-resistant adjustment mechanism to maintain pre-set pressure settings, enhancing system reliability and safety. Manufactured for the T-11A cavity, this valve is a robust solution for applications requiring precise load-holding and controlled lowering.
