Sun Hydraulics Valve | PBJB-LAN CKEB-XCN | DCEC-XYN DCED-XCN | High Pressure Cartridge Valve

Sun Hydraulics Series High-Pressure Cartridge Valves

Product Overview: Sun Hydraulics cartridge valves are globally recognized for their superior reliability, compact footprint, and high power density. This range spans from the precision counterbalance valve PBJB to pilot-operated check valves CKEB, and high-performance directional/proportional valves DCEC and DCED. Featuring a screw-in cartridge design, these valves integrate directly into manifolds, minimizing external plumbing and leakage risks. They are the premier choice for mobile machinery, industrial presses, and complex hydraulic control systems.

Featured models: PBJB-LAN, CKEB-XCN, DCED-XCN, and DCEC-XYN.

Key Technical Advantages:

• Screw-in Cartridge Architecture: This design enables exceptional installation compactness and durability against extreme vibrations and shocks, allowing for easy field replacement.

• High-Pressure Directional Control: Engineered for high-pressure duty cycles, the CKEB provides reliable pilot-to-open check functions, while the DCEC/DCED series ensures precise 4-way shifting and flow management.

• Superior Load Holding: The PBJB-LAN offers outstanding counterbalance pressure control, ensuring smooth and safe movement during load descent.

• Precision Adjustment Options: Available in multiple configurations (e.g., L-adjustment bolt, X-no adjustment), catering to various requirements for automation and manual intervention.

• Extreme Duty Durability: Hardened valve bodies and precision-ground sealing surfaces ensure low internal leakage and an extended service life across the full pressure range.

Detailed Specifications & Parameters:

• Featured Model Matrix:

  • PBJB-LAN: Pilot-assisted counterbalance valve for load control and pressure holding.

  • CKEB-XCN: Pilot-operated check valve with high-pressure locking to prevent actuator drift.

  • DCED-XCN / DCEC-XYN: Direct-acting solenoid directional valves (4-way) for actuator direction switching.

• Core Technical Specs:

  • Max Operating Pressure: Up to 35 MPa (350 bar).

  • Max Flow Capacity: Ranges from 30 L/min to 160 L/min depending on cavity size (e.g., T-11A, T-2A).

  • Seal Material Options: Buna-N or Viton for chemical and temperature compatibility.

  • Mounting Torque: Must be installed according to Sun Hydraulics standard cavity torque specs for optimal sealing.
