KMX 708-2L-00300 Main Control Valve OEM Diagnostic Guide
Use this professional diagnostic reference when evaluating hydraulic health on Komatsu PC200-7 machines:
| Hydraulic/Mechanical Symptom | Technical Cause Analysis | Tatan Factory-Grade Solution |
|---|---|---|
| 1. Boom / Arm Cylinder Drifting Downward in neutral hold | Internal spool bore wear or main safety relief valve seat erosion letting oil bypass to tank. | Install Tatan KMX 708-2L-00300 Main Control Valve assembly; flush hydraulic return filter. |
| 2. Sluggish Compound Movements under Load | Pilot pressure restriction or degraded spring tension inside distribution valve. | Check pilot pump output pressure (>3.9 MPa) or upgrade directly to a complete new valve assembly. |
| 3. Extreme Hydraulic Oil Overheating | Continuous internal leakage between high-pressure spool galleries. | Replace with a factory-tested Tatan monoblock control valve unit. |
| 4. External Oil Leaks Around End Caps | Hardened rubber O-rings or cracked pilot end caps. | Swap out compromised unit with our pressure-tested factory control valve assembly. |
