Sun Hydraulics Counterbalance & Check Valves for Heavy Machinery

Product Overview: Sun Hydraulics Cartridge Valves are globally recognized for their patented “Floating Style” design. This unique construction allows internal components to self-center during installation, neutralizing stresses caused by manifold machining tolerances or excessive torque. This ensures the spool remains sensitive and responsive even under high-pressure conditions up to 350 Bar. This category features premier models for heavy-duty load control: CBCG-LJN, CBCA-LHN, CBEA-LHN (Counterbalance/Load Holding), and CXED-XCN (Direct-acting Check).

Engineered for extreme duty cycles, these screw-in cartridges are the premier choice for excavators, crane outrigger locking, aerial work platforms, mining machinery, and any hydraulic integrated system requiring absolute safety and pressure retention.

Key Technical Advantages:

• Superior Load Management (CB Series): The CBCA and CBEA counterbalance valves provide precise overload protection and controlled load lowering, effectively eliminating actuator drift (cylinder creeping) under heavy loads.

• Patented Floating Technology: The unique two-piece floating construction significantly reduces the risk of spool binding caused by mechanical stress, enhancing operational repeatability.

• Absolute Sealing Integrity (CX Series): Components like CXED-XCN feature precision-honed seats to ensure a zero-leakage, metal-to-metal seal in the reverse position, guaranteeing circuit safety.

• Industrial Durability: Rated for operating pressures up to 350 Bar (5,000 PSI), designed to maintain stable performance in continuous, high-frequency industrial environments.
