Important Compatibility Notes
Four Machines, Three Generations
R110-7 and R215-7 belong to the -7 generation on the 31N6 block. R220-9 belongs to the -9 generation on the 31Q6 block. R330-9 uses a Parker block. Although R215 and R220 differ by only five in model number, they are a generation apart and the valves do not interchange. No single valve covers all four machines.
Different Valve Families
The prefixes are separate valve families: 31N6 for R210-7 / R215-7, 31N8 for R225-7 / R290 / R305LC-7, 31NA for certain -5 and -9 builds, 31Q6 for the 20 tonne -9 machines, 31Q8 for the 29 to 30 tonne -9 machines, 31QB for the 48 to 52 tonne machines and 31M8 for the R55. Trade listings print several of these in one title, which is not evidence that they interchange.
Component Identification
31N6-17400 and 31N6-17410 are main relief valves for the KMX15RA block, and solenoid valves are also sold under Hyundai valve searches. They are cartridge components selling for tens of dollars and appear beside complete control valves in the same results.
Condition Verification
Reconditioned and second-hand control valves carry the same numbers as new ones and are traded at a fraction of the price. The condition tier is stated in writing on our quotations.
