Sun Hydraulics Cartridge Valve | NFEC-LEN NFBC-LCN CNDC-XCN | Direct-acting Flow Control

Sun Hydraulics Direct-acting Flow Control & Check Cartridge Valves

Product Overview: Sun Hydraulics Cartridge Valves are globally recognized for their iconic “Floating Style” design. This unique construction allows internal components to self-center within the cavity, neutralizing internal stresses caused by installation torque or manifold machining tolerances. This ensures sensitive and accurate operation even under extreme pressures up to 350 Bar. This category features the direct-acting flow and directional control series, including models: NFEC-LEN, NFDC-LAN, NFBC-LCN (Fully adjustable pressure-compensated flow control) and CNGD-XCN, CNHC-XCN, CNDC-XCN (Check valves).

Engineered for high-performance circuits requiring precision and integration, these valves are the premier choice for construction machinery, machine tool power units, agricultural equipment, and automated production lines.

Key Technical Advantages:

• Full Pressure Compensation (NF Series): Maintains a constant flow rate regardless of load pressure fluctuations, ensuring smooth speed control for actuators.

• Zero-Leakage Sealing (CN Series): Features hardened spools and seats to guarantee a perfect metal-to-metal seal in the closed position.

• Patented Floating Technology: The unique two-piece structure significantly reduces the risk of spool binding, enhancing overall system reliability.

• Compact Integration: The screw-in cartridge design streamlines manifold layouts, minimizes potential leak points, and reduces the total footprint of the hydraulic power unit (HPU).
