Product Description
Sun CBBDLKN
The Sun CBBDLKN is a high-performance, pilot-to-open check valve with a pilot assist feature, commonly known as a counterbalance valve. It is designed to control overrunning loads by creating back pressure and preventing the load from running ahead of the pump. This cartridge valve provides excellent load holding, smooth operational control, and thermal expansion relief for hydraulic actuators. The CBBDLKN is a screw-in cartridge valve that fits into the standard T-11A cavity, making it a versatile solution for integration into custom hydraulic manifolds and systems requiring precise motion and load control.
