CLSS 723-53-16202 Main Control Valve Assembly by Tatan Overview
The CLSS 723-53-16202 Control Valve assembly manufactured by Tatan is a heavy-duty monoblock hydraulic distribution unit belonging to our Main Control Valve Assembly classification. Engineered specifically for Komatsu WA380-6 and WA380Z-6 18-ton wheel loaders, replacing your worn control valve with a Tatan complete assembly eliminates bucket tilt creep, restores instantaneous lift boom speed, and cures internal pressure bypass across demanding aggregate quarry, batching plant, and earthmoving applications.
Operating under direct pressure flow from the loader’s hydraulic main pump and powered by the SAA6D107E-1 diesel engine, every genuine-grade CLSS 723-53-16202 Control Valve incorporates precision micro-lapped alloy spools, load-check poppets, electromagnetic bucket positioner detents, and an integrated boom float mechanism, ensuring 100% direct bolt-on installation with chassis hydraulic hard lines and pilot control hoses.

Wheel Loader Implement Hydraulic Flow Distribution & Multi-Spool Rebuild Matrix
Controlling 18-ton wheel loader lift arms and 3.3 m³ buckets under rapid loading cycles requires high-flow gallery integrity. When replacing or overhauling with the CLSS 723-53-16202 Control Valve, Tatan supplies complete factory-tested loader control valves, pilot detent solenoids, port relief cartridges, and complete seal rebuild kits across premier mobile hydraulic platforms:
⚖️ Load-Check Poppets
Factory-seated check valves lock bucket tilt and boom cylinders, eliminating uncommanded settling during truck loading.
⚡ Electromagnetic Detents
Pre-calibrated bucket leveler and boom kick-out detent coils ensure automatic release at preset dig angles.
🛠️ Micro-Lapped Spools
Precision-ground alloy steel spools with < 0.003 mm bore clearances eliminate high-pressure bypass and oil overheating.

CLSS 723-53-16202 Control Valve OEM Diagnostic & Troubleshooting Guide
Use this OEM manual hydraulic diagnostic guide to troubleshoot implement control valve symptoms on your Komatsu WA380-6 wheel loader:
| Hydraulic Symptom | Technical Cause Analysis | Tatan Factory-Grade Solution |
|---|---|---|
| 1. Loaded bucket tilts down / drifts while driving | Tilt circuit load-check valve poppet seat erosion or internal spool wear allowing high-pressure fluid leakage back to tank. | Replace with Tatan 723-53-16202 complete control valve assembly with factory pre-seated heavy-duty load check poppets. |
| 2. Boom float position sticking or bucket leveler fails to kick out | Electromagnetic detent coil burn-out or mechanical detent spring sleeve jammed by varnished hydraulic oil. | Clean detent mechanism galleries, verify 24V detent coil resistance, or install fresh pre-adjusted Tatan control valve. |
| 3. Sluggish boom raise while steering articulated loader | Steering priority demand valve spool sticking or main relief valve spring fatigue dropping pressure under 28.0 MPa. | Calibrate main relief valve popping pressure to 34.3 MPa boost setting and inspect steering priority flow balance. |
| 4. Hydraulic fluid temperature spikes rapidly under load (> 85°C) | Severe internal spool bypass between implement valve galleries caused by micro-scoring from abrasive silica dust. | Install Tatan new 723-53-16202 main control valve; flush hydraulic tank lines and install fresh 10μm return filter elements. |
