| No. | Question | Standard Answer |
|---|---|---|
| Q1 | Which excavator models fit proportional solenoid valve 225-4558? | This main pump proportional solenoid valve is specially designed for 320C and 330D medium-large excavator hydraulic pump regulator. |
| Q2 | What is the internal model and interchangeable OE code of this valve? | Cross reference OE short number is 2254558, built-in model number KDRDE5K-31/40E30. |
| Q3 | Do I need to disassemble the whole hydraulic pump during replacement? | No full pump disassembly required, plug and thread size match original, simple direct replacement. |
| Q4 | What typical machine faults can this proportional solenoid repair? | It solves insufficient digging power, slow arm/bucket movement, high fuel consumption and unstable pump output flow. |
| Q5 | What anti-interference design protects internal coil signal? | Thick multi-core anti-fatigue harness and fully sealed plug avoid signal disorder caused by vibration and dust. |
| Q6 | What DC voltage does this proportional coil support? | Standard DC24V, matching the universal power supply system of medium and large excavators. |
| Q7 | Why adopt double-layer fluorine rubber sealing structure? | Double seals effectively reduce hydraulic internal leakage even under long-time high pump pressure operation. |
| Q8 | Will the proportional control signal drift after long working hours? | High precision magnetic coil maintains stable signal without drift under continuous heavy load operation. |
| Q9 | What strict tests will each solenoid pass before delivery? | All units pass hydraulic flow test, coil resistance test, 200-hour continuous aging test and waterproof inspection. |
| Q10 | Can I buy one sample first to test matching on my 330D excavator? | Yes, single-piece sample order is supported for field matching and hydraulic performance test. |
