SUN Cartridge Valve Series | CBCA-LHN | RDHA-LSN | CKEB-XAN | CXCB-XAN | 6303413

Industrial Threaded Cartridge Valves (CBCA, RDHA, CKEB, CXCB)

Product Overview:

This series of threaded cartridge valves serves as the cornerstone for complex logic control and safety protection in hydraulic systems. The product line includes CBCA counterbalance valves with superior load-holding capabilities, RDHA pilot-operated relief valves for precision pressure regulation, and CXCB/CKEB check valves for ensuring unidirectional flow and circuit locking. Manufactured from high-strength alloy steel and optimized for harsh industrial environments, these valves are widely used in mobile machinery, injection molding, and custom hydraulic manifolds.

Featured models include: CBCA-LHN (CBCALHN), RDHA-LSN (RDHALSN), CKEB-XAN (CKEBXAN), CXCB-XAN (CXCBXAN), RVCF-XCV, and part number 6303413.

Key Technical Advantages:

• Multifunctional Integration: Offers a full spectrum of control from simple check functions to complex pressure-compensated counterbalance modulation.

• Zero-Leakage Load Holding: The CBCA and CKEB series utilize precision-ground spools to ensure zero-drift cylinder positioning under static loads.

• Rapid Response Times: RDHA relief valves feature a pilot-operated structure for instantaneous response to pressure transients, protecting pumps and actuators.

• Global Cavity Compatibility: Fits standard T-11A, T-2A, and T-10A SUN-style cavities for simplified installation and maintenance.
