Sun Hydraulics CBBA-LHN 3:1 Restrictive Counterbalance Cartridge Valve
Genuine Sun Hydraulics restrictive counterbalance cartridge valve designed for load holding, motion control, and overrunning load applications in industrial and mobile hydraulic systems.
The integral check valve allows free flow toward the load, while the pilot-assisted counterbalance function controls flow from the load. This design helps provide controlled movement and load holding in compatible hydraulic circuits.
