Description
CLSS 723-44-13101 Main Control Valve Assembly by Tatan Overview
The CLSS 723-44-13101 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 WA470-6, WA470-6A, and WA480-6 24-ton mining wheel loaders, replacing your worn control valve with a Tatan complete assembly eliminates bucket tilt creep, restores instantaneous boom hoist speed under 4.5 m³ quarry loads, and cures internal pressure bypass across demanding aggregate quarry, cement plant, and heavy bulk-handling applications.
Operating under direct pressure flow from the loader’s hydraulic main pump and powered by the 204 kW SAA6D125E-5 diesel engine, every genuine-grade CLSS 723-44-13101 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.

24-Ton Wheel Loader Implement Hydraulic Distribution & Multi-Spool Rebuild Matrix
Controlling 24-ton wheel loader lift arms and 4.5 m³ buckets under rapid loading cycles requires high-flow gallery integrity. When replacing or overhauling with the CLSS 723-44-13101 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.
Application Scenarios & Buyer Value
When upgrading or replacing your wheel loader hydraulic distribution system with our CLSS 723-44-13101 Control Valve, buyers achieve maximum operational uptime and flow control:
| Application Scenario | Value Delivered to Buyer |
|---|---|
| Komatsu WA470-6 Valve Replacement | 1:1 direct bolt-on installation eliminates 4.5 m³ bucket settling and restores snappy boom raise and dump speeds. |
| Hydraulic Overhaul Workshops | Avoids the complex labor of internal bore honing; saves mechanic hours with a pre-adjusted, factory-tested unit. |
| Quarry & Aggregate Batching Plants | Heavy-duty alloy spools withstand continuous 34.3 MPa relief pressures during harsh blasted rock scooping and truck loading. |
| Heavy Equipment Parts Stockists | Fast-moving, high-demand 24-ton loader control valve inventory ready for immediate shipment to minimize customer downtime. |
CLSS 723-44-13101 Control Valve OEM Diagnostic & Troubleshooting Guide
Use this OEM manual hydraulic diagnostic guide to troubleshoot implement control valve symptoms on your Komatsu WA470-6 wheel loader:
| Hydraulic Symptom | Technical Cause Analysis | Tatan Factory-Grade Solution |
|---|---|---|
| 1. Loaded 4.5 m³ 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 723-44-13101 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 under 204 kW output. | Install Tatan new 723-44-13101 main control valve; flush hydraulic tank lines and install fresh 10μm return filter elements. |
