SUN Hydraulics Cartridge Valve | CNCE-XCN | SCEA-LAN | RSFC-LEN | CBBL-LJN

Industrial Precision Cartridge Valves (Logic, Relief, and Counterbalance)

Product Overview:

This series of precision Threaded Cartridge Valves serves as the backbone for high-integration hydraulic control systems. The CNCE-XCN and SCEA-LAN logic valves utilize pilot signals for rapid circuit switching and directional control, while the RSFC-LEN direct-acting relief valve provides precise overpressure protection. For applications requiring safe load retention, the CBBL-LJN and CACG-LGN counterbalance valves ensure smooth operation of cylinders or motors across all load conditions through optimized pilot ratios.

Featured models include: CNCE-XCN, SCEA-LAN, RSFC-LEN, CBBL-LJN, and CACGLGN.

Key Technical Advantages:

• Efficient Logic Modulation: The CNCE and SCEA series logic elements are designed for high response and ultra-low pressure drop, making them ideal as main directional control units for high-flow circuits.

• High-Precision Pressure Protection: The RSFC-LEN relief valve utilizes a direct-acting balanced piston design with low hysteresis, effectively preventing transient system overpressure.

• Superior Load Balancing: CBBL and CACG counterbalance valves are engineered to eliminate chatter. Their pilot ratios (e.g., 3:1 or 4.5:1) allow real-time modulation based on load changes for smooth descent.

• Standard Cavity Compatibility: Fits standard T-11A, T-10A, and T-2A cavities, significantly reducing design complexity and maintenance costs for hydraulic manifolds.
