Sun Series High-Performance Hydraulic Cartridge Valves

Product Overview: This series of screw-in cartridge valves is engineered for high-density hydraulic manifolds, featuring industry-leading functional versatility. Unlike conventional valves, this range—including counterbalance, sequence, and logic valves—utilizes a unique floating construction. This design compensates for manifold machining variations and prevents internal component binding. From the CA-11A for load holding to the SC-11A for pressure control, these valves deliver high pressure ratings and exceptional service life across mobile and industrial applications.

Featured models include: CA-11A-3E-G-L-16, SC-11A-30-A-L-12, DC-62A-6E-10-N-12, PW-21A-40-D-8, and LC-19A-3C.

Key Technical Advantages:

• Floating Style Design: Protects internal moving parts from deformation caused by excessive installation torque or manifold misalignment, ensuring smooth operation.

• High Pressure Ratings: Optimized for heavy-duty conditions with operating pressures up to 350 bar (5000 PSI).

• Precision Adjustment Options: Features multiple adjustment types (e.g., L-style adjusters) for precise on-site calibration of pressure or flow.

• Corrosion Resistance & Durability: Manufactured from high-strength alloy steel with hardened wear surfaces to ensure low leakage and long-term reliability in harsh environments.
