Sun Hydraulics Pilot-to-Open Check Valve CKCB-XCN
Typical Application Scenarios
This valve is classified as a "locking valve" rather than a motion control or counterbalance valve. Its primary functions are to provide a hydraulic lock that prevents cylinder drift and to offer hose-burst protection.
1. Attachment Equipment: Forklift attachments such as paper roll clamps, flat clamps, and soft-bale clamps; it maintains clamping pressure mechanically over extended periods to prevent load drops.
2. Construction Machinery: Heavy-duty outrigger cylinder locks for cranes and truck-mounted cranes, preventing outrigger retraction during lifting operations.
3. Agricultural Machinery: Safety pressure maintenance for cylinders in reversible plows and lifting platforms.
Core Valve & Seal Components
| No. | Component Name | Specification & Core Technical Parameters | Qty / Loop | Repair & Replacement Recommendation |
|---|---|---|---|---|
| 1 | Pilot-to-Open Check Valve Cartridge | Model: CKCB-XCN Mounting Thread: M20×1.5 (High-quality metric interchangeable version) |
1 pc | Core Component. If the cylinder fails to hold pressure (drifting), it is mostly due to the valve seat being scratched by metal debris. The full cartridge must be replaced. |
| 2 | External Step Multi-Layer Seal Kit | Metric/Imperial universal specifications. Material: Buna-N (Nitrile) Includes O-rings and anti-extrusion back-up rings. |
1 set | Must be replaced upon disassembly. Contains all seal rings on the cartridge steps. Once the cartridge is unscrewed for inspection, new seals must be used during reassembly to prevent external leaks. |
| 3 | Pilot Port Filter Screen (Optional) | Material: Stainless steel wire mesh. Filtration rating: 150 - 200 mesh. |
1 pc | Highly recommended. Installed before the pilot control port (Port 3) to prevent main loop debris from entering the pilot chamber and seizing the valve spool. |
Manifold Body, Fittings & Lines
| No. | Component Name | Description & Material Specifications | Qty / Loop | Repair & Replacement Recommendation |
|---|---|---|---|---|
| 4 | 3-Port Metric Single Valve Manifold Block | Material: High-tensile ductile iron (High-pressure grade). Cavity Thread: M20×1.5. |
1 pc | Replace if damaged. The standalone block holding the cartridge valve. Must be replaced if internal threads strip, sealing faces crack, or the internal cavity erodes. |
| 5 | High-Pressure Hydraulic Adapters | Thread type: M20×1.5 converted to various bite-type or flared fitting sizes. | 3 pcs | Replace as needed. Connectors for the inlet port, load port, and pilot port. Check threads and cone seals for dents or deformation during overhauls. |
| 6 | Bonded Seals / ED Rings | Size: Fits face seals of M20 / G3/8 etc. pipe fittings. | 3 pcs | Must be replaced. Metal bonded washers at the interface of adapters and manifold. These are single-use compression deformation seals and must be replaced during overhauls. |
