Product Description
Sun CBBDLJN
The Sun CBBDLJN is a high-performance, pilot-to-open check valve with a pilot-assist feature, commonly known as a counterbalance valve. It is designed for reliable load holding and to control motion in hydraulic systems by preventing loads from running ahead of the pump. This cartridge-style 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. Its robust construction ensures durability and precise control in demanding applications. The CBBDLJN is designed to fit into a standard T-10A cavity, making it a versatile solution for integration into custom hydraulic manifolds.
