Doosan DH220-5 Main Control Valve Assembly Overview
The Doosan DH220-5 Main Control Valve Assembly (OEM Part Numbers: 2302-9288, 2302-9288A, 401-00023, 2272-6015) manufactured by Tatan is a precision-engineered hydraulic distribution valve belonging to our Main Control Valve Assembly classification. Designed specifically for Doosan DH220-5, Solar 220LC-V, Solar 225LC-V, and DH225-7 20-to-22 ton excavators, replacing your worn hydraulic valve with a Tatan complete DH220-5 main control valve assembly eliminates hydraulic function hesitation, cylinder drift, and internal oil leakage instantly.
Built strictly according to original OEM specifications, this hydraulic control valve features micro-lapped alloy steel spools and ductile iron housing, ensuring 100% direct bolt-on fitment with pilot control lines and main hydraulic pump hoses. Every unit undergoes strict hydraulic pressure testing up to 34.3 MPa on specialized test stands before dispatch to guarantee zero oil leakage and immediate operational readiness for earthmoving, digging, and quarry mining projects.

Doosan DH220-5 Main Control Valve Assembly OEM Diagnostic Guide
Use this OEM manual hydraulic diagnostic guide to troubleshoot operational control valve symptoms on your Doosan DH220-5:
| Hydraulic Symptom | Technical Cause Analysis | Tatan Factory-Grade Solution |
|---|---|---|
| 1. Slow boom/arm speed & cylinder drifting down | Main relief valve pressure drop below 34.3 MPa or internal spool wear allowing oil bypass to return tank. | Install Tatan new DH220-5 main control valve assembly; flush hydraulic system & replace oil filter. |
| 2. Jerky or delayed lever response when operating travel/swing | Pilot control spool sticking, clogged pilot line filter, or pilot signal pressure leak (<3.9 MPa). | Clean pilot lines, inspect pilot pressure, or replace complete DH220-5 hydraulic distribution valve. |
| 3. Hydraulic oil overheating rapidly during excavation | Internal valve spool bypass generating excessive friction heat or stuck overload port relief valve. | Calibrate main relief pressure or swap to a Tatan factory pre-tested DH220-5 main control valve. |
| 4. External hydraulic oil leaking between valve sections | Sectional seal O-ring degradation or cracked valve body from high hydraulic shock pressure spikes. | Replace with Tatan high-density ductile iron main control valve assembly with reinforced seals. |
