| No. | Question | Standard Answer |
|---|---|---|
| Q1 | Which medium excavators adopt CLSS closed load sensing solenoid valve 702-21-07610? | This flange CLSS proportional solenoid is specially manufactured for PC200-8 and PC220-8 medium construction excavator hydraulic pump regulator manifold block. |
| Q2 | What upgrade does closed load sensing bring compared with open-loop proportional valves? | It forms closed signal feedback loop between pump and main valve, realize real-time dynamic power adjustment, reduce energy loss and achieve lower fuel consumption under mixed working conditions. |
| Q3 | What abnormal machine performance will appear if the original solenoid fails? | Unstable hydraulic output under variable load, frequent engine stall during rock breaking, delayed boom and stick movement, continuously rising hydraulic oil temperature. |
| Q4 | Is full disassembly of hydraulic main pump required to replace this flange solenoid? | No, external flange bolt fixed 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 high-temperature oil-resistant wire and fully sealed two-pin plug resist long-term vibration, dust and high heat interference. |
| 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 closed load sensing control effect on excavator on site. |
