| No. | Question | Standard Answer |
|---|---|---|
| Q1 | Which excavator models use proportional cartridge solenoid valve 485-9850-03? | This load sensing proportional screw-in solenoid is specially manufactured for 320GC and 330GC medium-large excavator hydraulic pump regulator manifold block. |
| Q2 | What unique load sensing function does this valve realize? | It automatically adjusts main pump flow according to digging load, reduce unnecessary hydraulic output and realize energy-saving operation. |
| Q3 | What abnormal performance will appear once the original solenoid fails? | Unstable digging strength, lagging boom and bucket action, fluctuating pump pressure and obvious fuel consumption rise. |
| Q4 | Is complete disassembly of hydraulic pump required during replacement? | No, independent screw-in cartridge design allows single-piece quick replacement without splitting the whole pump assembly. |
| Q5 | What structural design avoids signal disorder in harsh construction environment? | Thickened multi-core oil-resistant harness and fully sealed square plug effectively resist dust, vibration and high temperature interference. |
| Q6 | Can single sample be supplied for field hydraulic performance test before bulk order? | Yes, single-piece sample order is supported to check fitting condition and load sensing control effect on excavator on site. |
