| No. | Question | Standard Answer |
|---|---|---|
| Q1 | Which medium excavators adopt proportional solenoid valve 627-2304? | This flow limiting flange proportional solenoid is specially manufactured for 320GC and 330GC medium construction excavator hydraulic pump regulator manifold block. |
| Q2 | What energy-saving flow limiting function does this valve realize? | It dynamically limits main pump hydraulic flow according to working load, cut redundant hydraulic output and realize low fuel consumption operation for long-hour construction. |
| Q3 | What abnormal machine performance will occur if the original solenoid fails? | Unstable digging strength, delayed boom and stick movement, fluctuating pump pressure and obvious continuous rise of hydraulic oil temperature. |
| Q4 | Is full disassembly of hydraulic main pump required to replace this flange solenoid? | No, external flange bolt fixing design allows single-piece quick replacement without splitting the whole pump assembly. |
| Q5 | What anti-interference design guarantees stable signal in harsh construction environment? | Thickened multi-core oil-resistant wire and fully sealed two-pin plug resist long-term vibration, dust and high temperature interference effectively. |
| Q6 | Can single sample be supplied for field hydraulic performance test before bulk purchase? | Yes, single-piece sample order is supported to check fitting condition and flow limiting control effect on excavator on site. |
