| No. | Question | Standard Answer |
|---|---|---|
| Q1 | Which large excavators adopt main control pilot solenoid valve 702-21-58100? | This square block pilot proportional solenoid is specially manufactured for PC300-7 and PC360-7 large construction excavator main multi-way control valve pilot oil circuit. |
| Q2 | What core pilot pressure regulation function does this valve undertake in hydraulic system? | It receives ECU current signal to adjust output pilot oil pressure, control the opening stroke of main valve spool, realize stepless speed regulation of boom, arm and bucket actions. |
| Q3 | What abnormal machine states will appear if this pilot solenoid fails? | Slow boom & bucket movement, insensitive operation handle, insufficient breakout force, unstable idle action and continuous 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 main valve block, only four fixing bolts and wiring plug need to be removed for direct replacement, low maintenance difficulty. |
| Q5 | What structural design ensures stable signal output in harsh construction environment? | Thickened braided oil-proof wire + fully sealed two-pin waterproof connector, integral anti-rust alloy valve block, effectively resist long-term dust, vibration and high temperature interference. |
| Q6 | How to quickly judge whether the solenoid coil is damaged before installation? | Use multimeter to measure coil resistance, normal range 14–16 ohms; infinite resistance means open circuit, resistance lower than 10 ohms means coil short circuit. |
