| No. | Question | Standard Answer |
|---|---|---|
| Q1 | Which large heavy excavators adopt LS load sensing main pump solenoid valve 708-2H-25240? | This square flange LS proportional solenoid is specially manufactured for PC400-7 and PC450-8 large mining construction excavator variable hydraulic pump regulator oil circuit. |
| Q2 | What core LS load sensing function does this valve realize for large excavator hydraulic system? | It collects real-time load signal from main valve, adjusts pump output pressure and flow in closed loop, matches engine power output, reduces unnecessary hydraulic loss and lowers fuel consumption during long-time heavy mining work. |
| Q3 | What abnormal machine performance will occur if the original solenoid fails? | Frequent engine stall under heavy rock excavation, unstable breakout force, slow boom & bucket movement, fluctuating pump pressure and continuous sharp rise of hydraulic oil temperature. |
| Q4 | Is full disassembly of the whole hydraulic main pump required during replacement? | No, this valve is externally mounted on pump regulator block; only four fixing bolts and wiring plug need to be removed for direct replacement, low maintenance difficulty and short repair period. |
| Q5 | What anti-interference design guarantees stable signal output under harsh mine environment? | Thickened corrugated oil-resistant protective wire + fully sealed two-pin waterproof connector, integral rust-proof alloy valve body, effectively resist long-term mine dust, strong vibration 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 verify installation matching and LS load sensing power regulation effect on mining excavator on site. |
