Sun Hydraulics Cartridge Valve | CBFC-LIN CBBC-LIN CXBA-XAN | Counterbalance & Check

Sun Hydraulics CXBA, LPFC, CBFC & CBBC 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 load control and flow logic: CBFC-LIN, CBBC-LIN (Counterbalance), CXBA-XAN / XBN (Check Valve), and LPFC-XGN (Pilot Logic Element).

Engineered for high-pressure, long-life, and severe-duty hydraulic integrated circuits, these screw-in cartridges are the premier choice for construction machinery, mobile equipment outrigger locking, aerial work platforms, and industrial Hydraulic Manifolds.

Key Technical Advantages:

• Superior Load Management (CB Series): The CBFC and CBBC counterbalance valves provide precise deceleration control and safety locking, effectively eliminating actuator drift under load.

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

• Logic Control Flexibility (LP Series): The LPFC pilot-operated logic element enables rapid high-flow switching, optimizing energy efficiency within complex circuits.

• Absolute Sealing Integrity: The CXBA check valve series features precision-honed seats to ensure a zero-leakage, metal-to-metal seal in the reverse position.
