The Sun Hydraulics CBCALHN is a high-performance, pilot-to-open check valve with a pilot-assisted relief function, commonly known as a counterbalance valve. It is designed to control overrunning loads, providing smooth and stable motion control by preventing the load from running ahead of the pump. The CBCALHN also serves as a load-holding device, locking a load in any position. As a cartridge-style valve, it is engineered for installation into a T-11A cavity, making it a versatile solution for a wide range of mobile and industrial hydraulic applications. Its robust construction ensures reliability and a long service life in demanding environments.
