| No. | Question | Standard Answer |
|---|---|---|
| Q1 | Which excavator fits main pump proportional solenoid KDRDE5K-20/40C04 SKX5P-17? | This 24V EPPR proportional cartridge valve is specially designed for Hyundai R225-7, also compatible with R210LC-7, R140LC-7 7-series excavators with Kawasaki K3V112DT main pump. |
| Q2 | What is the core working function of this pump proportional solenoid? | It adjusts the swash plate angle of the variable main pump by changing pilot pressure, matches engine power and hydraulic output, and prevents engine stall during heavy load excavation. |
| Q3 | What machine faults will appear if this solenoid fails? | Severe loss of digging power, unstable pump pressure, jitter during operation, slow movement of boom and arm, and continuously rising hydraulic oil temperature. |
| Q4 | Do I need to disassemble the entire hydraulic main pump during replacement? | No, it adopts standard threaded cartridge structure; only pull out the old valve core assembly and screw the new one in, no need to split the main pump housing. |
| Q5 | What wear-resistant process ensures long service life under high pressure oil? | The whole spool adopts ion nitriding hardening treatment, matched double high temperature HNBR sealing rings, fully sealed green waterproof plug, resist long-term hydraulic oil corrosion and frequent vibration. |
| Q6 | What voltage system does this proportional solenoid adapt to? | Standard DC24V, matched with the original electrical system of Hyundai 7-series excavators, cannot be interchanged with 12V coil versions. |
| Q7 | How to quickly judge coil damage before installation? | Use a multimeter to measure coil resistance, normal range 14–16 ohms; infinite resistance means open circuit, resistance lower than 9 ohms indicates internal short circuit and cannot be installed. |
