Sun Hydraulics Cartridge Valve | CKCB-XCN CWGG-LGN CWGL-LGN CXDA CXFA | Load Control

Sun Hydraulics CKCB, CWGG, CWGL & CXDA Series Cartridge Valves

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 load holding and directional control: CKCB-XCN (Pilot-to-open Check), CWGG-LGN / CWGL-LGN (Counterbalance/Load Holding), and CXDA-XAN / CXFA-XBN (Direct-acting Check).

Engineered for high-pressure, long-life, and severe-duty hydraulic integrated circuits, these screw-in cartridges are the premier choice for construction machinery outrigger locking, crane winch circuits, aerial work platforms, and industrial hydraulic manifolds.

Key Technical Advantages:

• Superior Load Management (CW/CK Series): The CWGG and CWGL counterbalance valves provide precise overload protection and safety locking, effectively eliminating actuator drift 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.

• High-Integrity Sealing (CX Series): Components like CXDA and CXFA feature precision-ground seats to ensure a zero-leakage, metal-to-metal seal even at maximum rated pressures.

• Optimized Adjustment (LGN/XCN): Adjustment options like the “L” type leak-proof screw provide superior sensitivity and setting stability during field commissioning.
