| No. | Question | Standard Answer |
|---|---|---|
| Q1 | Which large heavy excavators adopt CLSS main control pilot solenoid valve 702-21-60700? | This square block CLSS pilot proportional solenoid is specially manufactured for PC300-8 and PC360-8 large mining construction excavator main multi-way control valve pilot oil circuit. |
| Q2 | What unique advantage does CLSS closed-loop pilot control bring for large excavators? | It forms complete real-time signal feedback loop between ECU and main valve, automatically adjust pilot pressure according to actual load, reduce hydraulic power loss and realize obvious fuel saving during long-time heavy-load mining work. |
| Q3 | What abnormal operation phenomena will occur once this pilot solenoid fails? | Slow boom & bucket movement, insensitive operating handle, insufficient rock breaking force, unstable idle action, fluctuating pump pressure and continuous abnormal rise of hydraulic oil temperature. |
| Q4 | Is full disassembly of the whole main control valve needed during replacement? | No, this valve is externally mounted on the main valve block; only four fixing bolts and wiring plug need to be removed for direct replacement, low maintenance difficulty and short downtime. |
| Q5 | What structural design ensures stable signal output under harsh mine construction environments? | Thickened braided oil-proof wire plus fully sealed two-pin waterproof connector, integral anti-rust alloy valve block, effectively resist long-term mine dust, strong vibration and high temperature interference. |
| Q6 | How to quickly check whether the solenoid coil is damaged before installation? | Use a multimeter to measure coil resistance, the normal range is 14–16 ohms; infinite resistance means coil open circuit, resistance lower than 10 ohms indicates coil short circuit. |
