Frequently Asked Questions
| No. | Question | Standard Answer |
|---|---|---|
| Q1 | Which excavator models fit proportional cartridge solenoid valve 485-5747? | This main pump proportional screw-in solenoid is specially designed for 320GC and 330GC medium-large excavator hydraulic pump regulator block. |
| Q2 | What interchangeable short OE number corresponds to 485-5747? | The cross reference short code is 4855747, two part numbers stand for the same complete proportional solenoid assembly. |
| Q3 | What core function does this proportional cartridge valve realize? | It realizes stepless adjustment of hydraulic pump displacement through electric signal, improve digging efficiency and cut fuel consumption. |
| Q4 | Do I need to fully disassemble the hydraulic pump during replacement? | No full pump disassembly required, independent screw-in design supports quick single-piece replacement. |
| Q5 | What typical hydraulic failures will be caused by damaged original solenoid? | Insufficient digging force, slow boom and bucket movement, unstable pump output and increased fuel consumption. |
| Q6 | What design prevents control signal disorder on construction sites? | Oil-resistant reinforced multi-core harness and fully sealed plug resist vibration and dust interference effectively. |
| Q7 | What advantages does double fluorine rubber sealing bring? | Double sealing structure greatly reduces internal oil leakage under long-term continuous high pump pressure operation. |
| Q8 | What strict quality tests will each solenoid pass before delivery? | Hydraulic proportional flow test, coil resistance inspection, 200-hour high temperature aging test and waterproof tightness test. |
| Q9 | Can I buy one sample to test matching performance on excavator before bulk order? | Yes, single-piece sample order is supported to check fitting and hydraulic working performance on site. |
