Description
HCV06 YB60002551 Control Valve Assembly Overview
The HCV06 YB60002551 Control Valve assembly manufactured by Tatan is a high-pressure multi-spool sectional hydraulic distribution unit belonging to our Main Control Valve Assembly classification. Engineered specifically for Hitachi ZX130-5G, ZX130K-5G, and ZX120-5A 13-ton excavators, replacing your worn valve with a Tatan complete assembly eliminates cylinder settling, balances dual-pump confluence digging power, and cures internal pressure bypass across demanding quarry and excavation applications.
Powered by the machine’s main hydraulic pump and matched with the Isuzu 4BG1 diesel engine platform, this HCV06 YB60002551 Control Valve incorporates precision micro-lapped alloy spools, load-check poppets, arm regeneration galleries, auxiliary breaker circuits, and an integrated straight-travel spool, ensuring 100% direct bolt-on installation with chassis hydraulic hard lines and pilot control hoses.

HCV06 YB60002551 Control Valve Diagnostic & Troubleshooting Guide
Use this technical guide to diagnose common hydraulic control valve issues on Hitachi ZX130-5G series excavators:
| Hydraulic Symptom | Technical Cause Analysis | Tatan Factory-Grade Solution |
|---|---|---|
| 1. Boom drops or drifts downward under heavy 0.59 m³ rock bucket | Boom holding check valve poppet seat wear or port relief valve O-ring leakage allowing pressurized fluid to pass to tank. | Replace with Tatan complete HCV06 YB60002551 Control Valve assembly with factory pre-seated holding check poppets. |
| 2. Sluggish compound digging (arm & boom slow together) | Arm regeneration spool sticking or internal dual-pump flow-merging check valve contamination failing to combine pump flow. | Disassemble and ultrasonic clean valve galleries; calibrate main relief valve popping pressure to 34.3 MPa (36.3 MPa boost). |
| 3. Machine veers off course when digging while traveling | Straight travel spool sticking or internal travel merge check valve seat wear causing unequal flow distribution to travel motors. | Inspect straight travel pilot pressure, clean spool bore, or replace complete main control valve assembly. |
| 4. External fluid seepage between valve sections | Tie-rod bolt elongation or inter-section fluororubber O-rings degraded from continuous oil temperatures over 80°C. | Install new Tatan sectional valve pre-torqued with industrial O-rings and calibrated tie-rod fasteners. |
