Product Description
Sun Hydraulics CBGA, RDDA, PRDB & NFDD 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: CBGA-LHN / CBGG-LJN (Counterbalance), RDDA-LCN (Direct-acting relief), PRDB-LDN (Pilot-operated reducing/relieving), and NFDD-LGN (Pressure-compensated flow control).
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 construction machinery, mobile cranes, aerial work platforms, and precision industrial equipment.
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 CBGA/CBGG series provides elite load locking and smooth descent control, ensuring maximum operational safety.
Dynamic Pressure Response: The RDDA relief valve delivers instantaneous overpressure protection, while the PRDB reducing valve maintains constant secondary pressure.
Load-Independent Speed Control: The NFDD series maintains precise and stable actuator speeds despite fluctuating load pressures.
