Product Description
Sun Hydraulics DLDF, CBGA, PBJB & NCCB 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: DLDF-MCN (Solenoid-operated directional), CBEG-LJN / CBGA-LHN (Counterbalance), PBJB-LWN / PRDB-LBN (Reducing/Relieving), NCCB-LCN (Needle valve), and LPJC-XGN (Logic element).
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 lifting machinery, aerial work platforms, excavators, and industrial automation systems.
Key Technical Advantages:
Floating Cartridge Technology: The unique two-piece construction significantly enhances operational reliability under extreme pressure and thermal cycles.
Precise Load Management: The CBEG/CBGA series provides elite load locking and smooth descent control, eliminating actuator drift.
Versatile Solenoid Control: The DLDF series offers rapid response times and multiple manual override options for system flexibility.
Stable Pressure Regulation: PBJB/PRDB series maintains constant secondary pressure for branch circuits, regardless of primary system fluctuations.
