Product Description
Sun Hydraulics RDDA, CWEA, DRAX & CXFA Series Cartridge Valves
Product Overview: Sun Hydraulics Cartridge Valves are globally recognized for their iconic “Floating Style” design, which allows internal components to self-center, minimizing internal stress and ensuring sensitive operation under extreme conditions. This category features premier models: RDDA-LAN/LCN (Direct-acting relief), CWEA-LHN (High-performance counterbalance), DRAX-LAN (Pilot-operated reducing), and the CVEV/CXFA precision logic elements.
Engineered for high-pressure and long-life hydraulic circuits, these screw-in cartridges integrate seamlessly into custom manifolds. They are the premier choice for construction cranes, aerial work platforms, CNC machinery, and industrial Hydraulic Power Units (HPU).
Key Technical Advantages:
Floating Cartridge Technology: The unique two-piece floating construction prevents spool binding caused by manifold machining tolerances, significantly enhancing reliability.
Precise Load Holding & Safety: The CWEA series ensures smooth descent control, while the RDDA series provides instantaneous overpressure protection.
High-Response Logic Switching: CXFA and CVEV logic elements allow for efficient directional control and check-valve functions within integrated circuits.
Extended Durability: Hardened and precision-ground internal components ensure long service life even under continuous 350 Bar operational cycles.
