Sun Hydraulics Cartridge Valve | CBDG-CJN CBEA-LHN NFDD-LGN | Flow & Pressure Control

Sun Hydraulics CBDG, CBEA, NFDD & NFCC 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 control and flow management: CBDG-CJN / CBEA-LHN (Counterbalance), NFDD-LGN / NFCC-LCN (Pressure Compensated Throttle), RPCC-LCN / NCCC-LCN (Pilot-operated Control), and FCCB-LAN (Flow Control).

Engineered for high-pressure, long-life, and severe-duty hydraulic integrated circuits, these screw-in cartridges are the premier choice for construction machinery, mobile cranes, aerial work platforms, injection molding machinery, and industrial Hydraulic Power Units (HPU).

Key Technical Advantages:

• Superior Load Management (CB Series): The CBDG and CBEA 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 sensitivity.

• Precision Flow Compensation (NF Series): NFDD and NFCC series feature superior pressure compensation to maintain constant actuator speeds despite varying load pressures.

• High-Response Flow Control: The FCCB and RPCC series utilize pilot-operated logic for rapid response and precise flow regulation in complex hydraulic circuits.
