Sun Hydraulics Cartridge Valve | RVBB-LAN RVEB-LAN CXJA-XCN NFCC-LCN | Relief & Check

Sun Hydraulics RV, CX, NF & CO 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 during installation, neutralizing stresses caused by manifold machining tolerances or excessive torque. This ensures the spool remains sensitive and responsive even under high-pressure conditions up to 350 Bar. This category features premier models for pressure protection and flow management: RVBB / RVCB / RVEB / RVGB / RVIB / RVES (Pilot-operated Relief), CXJA / CXBA / CKEB / CODA (Check/Shuttle), and NFCC-LCN (Pressure Compensated Throttle).

Engineered for severe-duty hydraulic integrated circuits, these screw-in cartridges are the premier choice for construction machinery, mobile load-holding circuits, industrial Hydraulic Power Units (HPU), and high-pressure system safety.

Key Technical Advantages:

• Patented Floating Technology: The unique two-piece floating construction significantly enhances operational reliability under high-pressure cycles and minimizes internal leakage risks caused by mechanical stress.

• Precision Pressure Relief (RV Series): Pilot-operated designs ensure low pressure override and high repeatability, providing robust overload protection for the system.

• Zero-Leakage Integrity (CX/CO Series): Featuring precision-honed seats to ensure an absolute metal-to-metal seal in the closed position.

• Constant Flow Compensation (NF Series): The NFCC-LCN series features superior pressure compensation to maintain constant actuator speeds despite varying system load pressures.
