SUN Cartridge Valve | CBBG-LJN | CBDD-LJN | CCCA-LAN | CNHC-XCN | CXDA-XCN

High-Performance Cartridge Valves (CBBG, CBDD, CNHC, CXDA)

Product Overview:

This series of precision Threaded Cartridge Valves serves as the critical component for ensuring smooth actuator motion and system safety. The CBBG, CBDD, and CCCA series counterbalance valves are engineered to control overrunning loads, preventing cylinder drift while providing smooth descent modulation. The CNHC-XCN pilot-to-open check valve and CXDA-XCN free-flow check valve facilitate circuit isolation and flow direction protection. All valves are designed for standard SUN cavities (e.g., T-2A, T-11A) and are manufactured from high-strength steel for exceptional contamination tolerance and extended service life.

Featured models include: CBBG-LJN, CBDG-LJN, CBFG-LJN, CBHG-LJN, CCCA-LAN, CCEA-LAN, CBDD-LJN, CNHC-XCN, and CXDA-XCN.

Key Technical Advantages:

• Precision Load Holding: The counterbalance series (e.g., CBDD-LJN) offers various pilot ratios to ensure chatter-free cylinder movement and zero-drift locking under gravity loads.

• High-Response Check Control: The CXDA-XCN features ultra-low cracking pressures and optimized flow paths, ensuring minimal pressure drop even during high-flow cycles.

• Safety & Fail-safe Integrity: The CNHC-XCN pilot-to-open check valve is designed for critical safety circuits, ensuring immediate flow shut-off in the absence of a pilot signal.

• Modular Versatility: The threaded cartridge design allows for direct integration into hydraulic manifolds, reducing external plumbing and minimizing potential leakage points.
