| No. | Question | Standard Answer |
|---|---|---|
| Q1 | Which Hyundai excavators fit breaker solenoid valve 31Q6-91220? | This integrated aluminum block hydraulic hammer solenoid is specially manufactured for Hyundai R225LC-7, also compatible with R210LC-7, R140LC-9, R305-9 series construction excavators. |
| Q2 | What core hammer control function does this solenoid realize? | It receives ECU electrical signal to switch the auxiliary hydraulic oil circuit, control the high-pressure oil supply of hydraulic breaker, realize automatic start and stop of rock breaking hammer. |
| Q3 | What abnormal breaker faults will occur if this solenoid malfunctions? | Hydraulic hammer no striking force, intermittent hammer action, breaker cannot start, delayed hammer response, unstable pump pressure and continuously rising 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 two fixing bolts and unplug the wiring connector, no need to split the main hydraulic valve block. |
| Q5 | What wear-resistant high-pressure design adapts to long quarry operation? | Full nitriding hardened spool, double HNBR high-pressure oil-resistant sealing rings, solid anti-rust aluminum valve block, fully sealed two-pin waterproof plug, resist high-pressure hydraulic oil erosion, strong vibration and high heat. |
| Q6 | How to quickly check coil failure before installation? | Use multimeter to measure coil resistance, normal range 14–16 ohms; infinite resistance means coil open circuit, resistance below 9 ohms indicates internal short circuit and cannot be installed. |
