| No. | Question | Standard Answer |
|---|---|---|
| Q1 | Which Hyundai excavators fit proportional solenoid valve 31Q6-20131? | This integrated block pilot proportional solenoid is specially manufactured for Hyundai R220-9, also compatible with R140LC-9, R180LC-9, R290LC-9 9-generation hydraulic excavators. |
| Q2 | What core pilot pressure control function does this solenoid provide? | It receives ECU electrical signal to output linear proportional pilot oil pressure, adjust main valve spool opening stroke, realize stepless smooth speed control of boom, arm, bucket and swing actions. |
| Q3 | What abnormal hydraulic faults will occur if this solenoid fails? | Slow working movement, insufficient digging breakout force, delayed handle response, unstable pump pressure, shaking during operation and continuous high hydraulic oil temperature. |
| Q4 | Is complicated pipeline disassembly required during replacement? | No, the whole valve assembly is pre-integrated with internal oil passages, only remove the fixing bolts and plug the wiring connector, no need to split the main control valve body. |
| Q5 | What wear-resistant high-temperature design adapts to long-term construction work? | Full nitriding hardened spool, double HNBR high temperature oil-resistant sealing rings, integral anti-rust aluminum valve block, fully sealed two-pin waterproof plug, resist hydraulic oil corrosion, vibration and high heat. |
| Q6 | How to quickly inspect coil damage before installation? | Use multimeter to measure coil resistance, normal range 13–16 ohms; infinite resistance means open circuit, resistance below 9 ohms indicates internal coil short circuit and cannot be installed. |
