Sun Hydraulics Cartridge Valve | CXGE CXBA CBDG CBFA | Check & Counterbalance

Sun Hydraulics CX, CW & CB 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 check control and load holding: CXGE, CXCE, CXED, CXJA, CXBA (Check Valves) and CWCG, CBDG, CBFA (Counterbalance Valves).

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 Power Units (HPU).

Key Technical Advantages:

• Superior Load Management (CB Series): The CBDG and CBFA counterbalance valves provide precise deceleration control and safety locking, effectively eliminating actuator drift under heavy loads.

• Patented Floating Technology: The unique two-piece floating construction significantly reduces the risk of spool binding caused by mechanical stress, enhancing operational repeatability.

• Absolute Sealing Integrity (CX Series): Check valves like CXBA and CXGE feature precision-honed seats to ensure a zero-leakage, metal-to-metal seal in the reverse position.

• High Response & Flow Capacity: Optimized flow paths ensure high-pressure performance while maintaining low pressure drops and high flow rates.
