Sun Hydraulics Cartridge Valve | CKGB-XCN CBEG-LJN CBCA-LHN | Pilot Check & Counterbalance

Sun Hydraulics CKGB, CBEG, CBCA & PBDB Series Cartridge Valves

Product Overview: Sun Hydraulics Cartridge Valves are globally renowned for their iconic “Floating Style” design. This unique construction allows the internal spool to self-center during installation, effectively preventing spool binding caused by manifold machining tolerances or excessive installation torque. This category highlights a versatile range of premium models: CKGB-XCN (Pilot-to-open check), CBEG-LJN / CBCA-LHN / CBCG-LJN (Counterbalance), CXHA-XCN (Check valve), and PBDB-LWN (Pilot-operated reducing/relieving).

Engineered for high-pressure, long-life, and severe-duty hydraulic systems, these screw-in cartridges integrate seamlessly into custom manifolds. They are the premier choice for mobile cranes, aerial work platforms, excavators, and various industrial automation systems.

Key Technical Advantages:

• Floating Cartridge Technology: The unique two-piece construction significantly enhances operational reliability under extreme pressure and thermal cycles.

• Elite Load Management: The CBEG/CBCA/CBCG series provides superior load locking and smooth descent control, eliminating actuator drift.

• Zero-Leakage Sealing: The CKGB series ensures a perfect seal in the closed position, providing critical safety for hydraulic circuits.

• Stable Pressure Regulation: The PBDB series maintains constant secondary pressure for branch circuits, regardless of primary system fluctuations.
