The Sun CXFAXCN is a high-performance, pilot-assisted counterbalance valve designed for precise motion control and load-holding applications in hydraulic systems. As an externally drained valve, it ensures consistent performance regardless of back pressure at the outlet port. Engineered to fit the standard T-11A cavity, this cartridge valve provides smooth, stable operation for controlling overrunning loads on actuators like cylinders and motors. It also incorporates a thermal relief function to protect the circuit from pressure spikes caused by thermal expansion, enhancing system safety and reliability.
