Motor Grader Auxiliary Control Valve – Function and Interface Guide
This auxiliary hydraulic control valve must be matched to the exact motor grader system. First identify which blade, steering or auxiliary movement the valve controls. Similar-looking parts can use different internal or mounting details.
Ordering basis: Confirm controlled function, lever or pilot interface, ports, spool arrangement and settings before ordering.
Information buyers should provide
Machine model, serial number and installed location.
All casting, stamped or label numbers.
Clear photographs of every connection and mounting face.
Measurements for controlled function, lever or pilot interface, ports, spool arrangement and settings.
Diagnose the surrounding system
Inspect the mating components, fluid or mechanical condition and the original failure pattern. First identify which blade, steering or auxiliary movement the valve controls. Replacing the part without correcting contamination, misalignment or adjustment faults can cause repeat damage.
Installation and functional verification
Keep interfaces clean, compare the old and replacement parts side by side and follow the machine service procedure. After installation, check leakage, free movement, noise, temperature and the related machine function under controlled conditions.

FAQ
Can this auxiliary hydraulic control valve be matched from a photograph?
A photograph helps, but controlled function, lever or pilot interface, ports, spool arrangement and settings must also be verified.
What should be inspected before installation?
Check mating parts, mounting faces, lines or fasteners and the cause of the original failure.
Why are unverified model claims avoided?
The original record does not contain enough evidence to prove a specific model fitment.
Compatibility note: Final selection requires controlled function, lever or pilot interface, ports, spool arrangement and settings.
