Frequently Asked Questions
| No. | Question | Standard Answer |
|---|---|---|
| Q1 | Which large excavator models adopt proportional cartridge solenoid 491-0908? | This power matching proportional screw-in solenoid is exclusively produced for 336GC and 349GC large mining excavator hydraulic pump regulator manifold block. |
| Q2 | What unique power matching function does this valve realize? | It dynamically adjusts main pump flow output according to engine load to prevent engine stall during heavy rock excavation and optimize power utilization. |
| Q3 | What abnormal machine performance will appear if the original solenoid fails? | Frequent engine stall under heavy load, weak rock digging force, delayed boom action and continuous high hydraulic oil temperature. |
| Q4 | Do users need to fully disassemble the hydraulic main pump to replace this cartridge valve? | No independent screw-in cartridge design allows single-piece quick replacement without splitting the whole pump assembly. |
| Q5 | What anti-interference design ensures stable signal in harsh mine environment? | Thickened multi-core oil-resistant wire and fully sealed square plug effectively resist long-term vibration, dust and high temperature interference. |
| Q6 | Is single sample available for field hydraulic performance test before bulk purchase? | Yes, single-piece sample order is supported to verify fitting and power matching control effect on mining excavator on site. |
