Sun Hydraulics Cartridge Valve | CBGA-LHN CBCG-LJN CCGA-LAN | Counterbalance & Shuttle Valve

Sun Hydraulics CBGA, CBCG, CCGA & CBDA Series Cartridge Valves

Product Overview: Sun Hydraulics Cartridge Valves are globally recognized for their iconic “Floating Style” design, which allows internal components to self-center, minimizing internal stress and ensuring sensitive operation under extreme conditions. This category features premier models: CBGA-LHN / CBCG-LJN / CBDA-LHN (Counterbalance), CCGA-LAN (Shuttle valve), CAEA-LHN (Counterbalance), and the CXBA / CXAD precision check elements.

Engineered for high-pressure and long-life hydraulic circuits, these screw-in cartridges integrate seamlessly into custom manifolds. They are the premier choice for construction cranes, aerial work platforms, CNC machinery, and heavy-duty industrial Power Units (HPU).

Key Technical Advantages:

• Floating Cartridge Technology: The unique two-piece floating construction prevents spool binding caused by excessive installation torque, enhancing system reliability.

• Precise Load Holding: The CBGA/CBCG series ensures smooth descent control and zero-drift locking, guaranteeing operational safety.

• Efficient Logic Switching: The CCGA shuttle valve automatically switches between two signal sources with rapid and sensitive response.

• Extended Durability: Hardened and precision-ground internal components ensure long service life even under continuous 350 Bar operational cycles.
