The Sun CBGHLJN is a high-performance, pilot-assisted counterbalance valve with an integral check valve. Designed to fit into a standard T-11A cavity, this cartridge valve is engineered to control overrunning loads, preventing uncontrolled movement of actuators like cylinders or motors. It provides smooth, stable, and modulated motion control by maintaining a set pressure on the actuator. The integral check valve allows for free flow from the directional valve (port 2) to the load (port 1), while the pilot-assisted relief valve function controls the flow from port 1 to port 2. The CBGHLJN is ideal for applications requiring reliable load holding, thermal expansion relief, and protection against hydraulic line failure.
