The 803098168 Left Multi‑way Valve is a genuine OEM hydraulic control component manufactured by XCMG for motor graders and heavy construction equipment. This precision‑engineered sectional valve bank controls the flow of hydraulic oil to left‑side implements including blade lift cylinders, circle rotation, and optional attachments on XCMG GR series graders.
Engineered from high‑strength cast iron with hardened steel spools and wear‑resistant seals, the 803098168 multi‑way valve withstands operating pressures up to 16 MPa (2,320 psi) and extreme vibration in demanding grading applications. It directly replaces leaking, sticking, or worn left side valve sections on XCMG GR135, GR165, GR180, GR215, GR260, GR300, and GR350 motor graders.
Each unit features a sectional construction that allows for individual service of each spool section. The load‑sensing design ensures proportional flow distribution to multiple actuators simultaneously, providing smooth, coordinated blade movements even under partial flow conditions. The 803098168 is a direct bolt‑on replacement with identical porting and mounting dimensions to the original factory valve.

The XCMG 803098168 Left Multi‑way Valve is the central control hub for the left‑side hydraulic functions of your motor grader. It receives pressurized oil from the variable displacement piston pump and distributes it to the left blade lift cylinder, circle rotation motor, and optional attachments such as a rear ripper or front blade angle cylinders. The valve’s load‑sensing feature continuously monitors the pressure demands of each active function and adjusts flow accordingly, ensuring that the highest‑demand operation always receives priority[reference:1].
When multiple functions are activated simultaneously—for example, raising the left blade while rotating the circle—the 803098168 uses pressure‑compensated spools to allocate flow proportionally. This prevents any single function from starving others, maintaining smooth, predictable machine behavior. This is essential for fine grading applications where even small jerks can ruin the finished surface[reference:2].
The sectional construction of the 803098168 allows individual sections to be removed for service without replacing the entire valve bank. Each section corresponds to a specific hydraulic function (e.g., left lift, circle rotate, ripper raise/lower), making troubleshooting and repair efficient and cost‑effective.
The 803098168 employs a load‑sensing (LS) network that communicates the highest active load pressure back to the variable displacement pump. The pump then adjusts its swashplate angle to deliver exactly the flow required, no more, no less. This results in lower fuel consumption, reduced heat generation, and longer component life compared to fixed‑displacement systems[reference:3].
The valve includes integrated pressure compensators on each spool section. If the pump cannot meet the total flow demand (e.g., at low engine RPM), the compensators ensure that the available flow is shared proportionally among all active functions. This feature is critical when performing complex grading passes that require simultaneous blade lift, circle rotation, and articulation adjustments.
XCMG’s load‑sensing multi‑way valves are designed to work seamlessly with the company’s variable piston pumps, creating a highly efficient, responsive hydraulic system. The 803098168 is calibrated at the factory to match the flow and pressure requirements of GR series graders, ensuring plug‑and‑play replacement with no additional tuning required[reference:4].
Each 803098168 multi‑way valve is manufactured in XCMG’s ISO 9001:2015‑certified hydraulic facility. The valve body is cast from high‑grade ductile iron (GGG‑50) for exceptional strength and pressure retention. The spools are machined from case‑hardened steel, then ground and honed to a mirror finish (Ra ≤ 0.2 µm) to ensure smooth, stick‑free operation and minimal internal leakage.
The valve sections are assembled using precision‑ground tie rods that are torqued to exact specifications, ensuring perfect alignment and leak‑free sealing between sections. All dynamic seals are made from high‑grade nitrile rubber (NBR) or optional Viton for high‑temperature applications, providing long life even in demanding environments.
XCMG tests every valve at 150% of rated pressure (24 MPa / 3,480 psi) to verify structural integrity. Each spool is cycled 50,000 times under load to confirm wear resistance and seal durability. Only valves that pass these rigorous tests are approved for sale as genuine XCMG components.
Aftermarket multi‑way valves often use lower‑grade castings that can crack under pressure, or spools with poor metering characteristics that cause jerky, unpredictable blade movement. The genuine XCMG 803098168 is manufactured to the same specifications as the original factory valve, guaranteeing identical flow characteristics, porting, and mounting dimensions.
Counterfeit valves may omit critical internal components such as load‑sensing orifices or pressure compensators, resulting in poor multi‑function performance. The 803098168 includes all factory‑specified internal elements, ensuring that your grader maintains its original performance and fuel efficiency.
XCMG provides a 12‑month warranty against manufacturing defects. Each valve is serialized for traceability. This supersedes older numbers 803098001 and 803098045, with improved spool coatings and more durable seals for extended service life.
Common symptoms of a failing multi‑way valve include: sluggish blade response, blade drift (uncommanded movement), jerky or erratic cylinder motion, excessive oil heating, or external leakage from valve section joints. Also, if the grader struggles to perform multiple functions simultaneously (e.g., raising the blade while rotating the circle), the valve’s internal compensators may be worn.
Preventive replacement is recommended every 8,000 operating hours or when the valve shows signs of internal wear such as increased spool leakage (measured by cylinder drift rates). The cost of a genuine replacement valve is minimal compared to the cost of lost productivity from an unresponsive grader.
When replacing a valve, always use new O‑rings and sealing washers. Flush the hydraulic system before installation to remove any contaminants that could damage the new valve’s precision spools. Keep a spare 803098168 valve in your parts inventory for emergency replacements.
