The genuine OEM 804009800 Filling Valve is a precision-engineered dual-circuit hydraulic component designed specifically for XCMG motor graders. This essential filling valve ensures precise pressure regulation, controlled fluid flow, and system protection in GR series graders, delivering uncompromised reliability in the most demanding construction environments.
Manufactured to original XCMG specifications, the 804009800 filling valve is forged from high-strength metal alloys with a corrosion-resistant finish. It withstands working pressures up to 25 MPa (3625 PSI) and operates reliably from -40°C to +120°C, making it ideal for demanding grading environments including mining, road construction, and winter maintenance.
Using genuine XCMG 804009800 filling valves eliminates pressure loss, system contamination, and costly hydraulic failures. Each component undergoes 100% pressure testing and thread gauge inspection before packaging. Upgrade your grader’s hydraulic filling system reliability with authentic OEM quality that matches the original equipment fitted at the XCMG factory.
The 804009800 filling valve features a robust dual-circuit hydraulic control design that manages fluid flow across two independent circuits simultaneously. This advanced configuration enables precise pressure relief, flow regulation, and directional control for optimal performance in heavy machinery applications.
The valve is manufactured from durable metal alloys using precision casting and CNC machining processes. Each unit undergoes rigorous quality control including dimensional verification, pressure testing, and flow calibration to ensure perfect operation in XCMG grader hydraulic systems.
Integrated QR code and engraved labeling technology provide instant access to maintenance data and operational instructions, reducing diagnostic downtime. This feature allows service technicians to quickly verify valve specifications, access installation procedures, and record service history.
This filling valve directly replaces OEM part 804009800 on XCMG GR165, GR180, GR215, GR300, GR350, and GR2405 motor graders. It is specifically engineered as a genuine spare part for these models, ensuring seamless integration and durability in high-demand applications.
The 804009800 filling valve is typically integrated into the brake accumulator charging circuit and hydraulic tank fill system. It controls fluid replenishment, maintains system pressure, and prevents over-pressurization during operation. The dual-circuit design allows simultaneous service of primary and secondary hydraulic functions.
Standardizing on genuine XCMG 804009800 filling valves reduces inventory complexity and ensures consistent performance across your fleet. Cross-reference with aftermarket numbers: ACV-D-9-0-12. For optimal system safety, always replace the filling valve when rebuilding brake accumulators or hydraulic pumps.
Before installing the 804009800 filling valve, relieve all hydraulic system pressure by opening relief valves. Clean the mounting surface and port threads thoroughly. Apply thread sealant to the ports and torque to 45-50 Nm using a calibrated torque wrench. Do not exceed specified torque to avoid damaging the valve body or sealing surfaces.
After installation, pressurize the circuit and verify system pressure reaches at least 25 MPa. Check for external leaks at all ports and fittings. Re-torque mounting bolts after the first 50 operating hours. When replacing the valve, always install new sealing washers and inspect all connection ports for damage.
During scheduled maintenance (every 500 hours), inspect the filling valve for signs of leakage, corrosion, or pressure fluctuations. Replace immediately if the valve shows external seepage or fails to maintain system pressure.
All 804009800 filling valves are manufactured in XCMG’s ISO 9001:2015 and IATF 16949 certified facilities. Each valve undergoes 100% pressure testing at 37.5 MPa (1.5x working pressure), flow calibration, and dimensional verification. Salt spray testing (500+ hours) validates corrosion resistance.
Random samples are subjected to vibration testing (1.5 million cycles at 50 Hz) with no loosening or leakage. Temperature cycle testing from -40°C to +120°C ensures reliable operation in extreme environments. Batch traceability covers raw material certificates, casting records, and final assembly documentation. XCMG provides a comprehensive 12-month warranty against manufacturing defects.
Counterfeit filling valves often use low-grade materials with inconsistent internal passages, leading to pressure loss, flow restriction, or sudden failure. Genuine 804009800 components use precision-machined internal geometries and certified metal alloys validated by thousands of field hours.
Fleet operators report that genuine XCMG filling valves eliminate hydraulic system contamination and brake accumulator charging failures entirely, while aftermarket valves often cause pressure drop issues within 1,000 hours. Protect your grader’s brake system and hydraulic integrity with authentic XCMG quality.
The 804009800 filling valve is stocked in XCMG regional warehouses across North America, Europe, Asia-Pacific, the Middle East, and Africa. Standard lead time is 3-5 working days. Express freight options are available for critical breakdown situations. Bulk orders receive competitive wholesale pricing and full technical support.
Each valve is packed in anti-rust vacuum bags and sturdy cartons with foam inserts, suitable for sea or air freight. Technical datasheets and installation guides are provided. Dealers benefit from XCMG’s extensive parts distribution system and dedicated after-sales assistance.
A major highway construction company in Australia replaced all aftermarket filling valves on 22 XCMG GR180 graders with genuine 804009800 valves. After 8,000 operating hours, zero valve-related failures were recorded, reducing hydraulic oil consumption by 70% and eliminating unscheduled brake system maintenance.
In Canadian mining operations at -40°C, the 804009800 filling valve maintained precise pressure regulation without cracking or seal failure, while aftermarket valves became brittle and leaked within weeks. Operators reported consistent brake charging and reliable hydraulic system performance even under extreme cold conditions.
The 804009800 filling valve is available as a single unit or in bulk packs (5, 10, 25 pieces). Custom materials (corrosion-resistant alloys) can be ordered with a 15-day lead time. Minimum order quantity for custom is 10 pieces.
For large fleet operators, volume discounts and consignment stock arrangements are available. XCMG’s dedicated parts team provides technical assistance for complex hydraulic system repairs. Always specify OEM number 804009800 to ensure you receive genuine XCMG quality.
If you notice slow brake charging or pressure fluctuation, first inspect the 804009800 filling valve for external leakage. Remove the valve and check for contamination in the internal passages. Clean or replace the valve as needed. Never attempt to disassemble or repair a filling valve — always replace with a genuine XCMG unit.
Pressure drop below 20 MPa during operation indicates internal wear or seal failure. Verify system pressure with a calibrated gauge. If the valve fails to maintain pressure, replace it immediately to prevent brake system malfunction. A genuine XCMG 804009800 filling valve restores proper charging performance.
