Sun Hydraulics Cartridge Valve | NFCC-LCN CXDA-XCN LOHD-XDN | Pilot Check & Throttle

Sun Hydraulics NFCC, CXDA, LOHD & CAGA Series 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 premier models: NFCC-LCN/LAN (Pressure-compensated throttle check), CXDA-XCN/XAN (Check valve), LOHD-XDN (Pilot-to-open check), CAGA-LHN (Counterbalance), and CSAB-XXN (Fixed orifice).

Engineered for high-performance and compact hydraulic circuits, these screw-in cartridges integrate seamlessly into custom manifolds. They are the premier choice for mobile cranes, aerial work platforms, CNC machinery, and automated production lines.

Key Technical Advantages:

• Floating Cartridge Technology: The unique two-piece floating construction prevents spool binding, significantly enhancing system reliability under high-pressure cycles.

• Precise Flow & Directional Control: The NFCC series offers pressure compensation to maintain constant flow despite load changes, while the CXDA ensures absolute shut-off for unidirectional flow.

• Load Holding & Pilot Release: The LOHD and CAGA series provide elite locking for actuators, preventing cylinder drift caused by gravity loads.

• Highly Integrated Design: Minimizes external fittings and plumbing, effectively reducing leak risks and allowing for more compact hydraulic power unit (HPU) designs.
