| No. | Question | Standard Answer |
|---|---|---|
| Q1 | Which excavators match 24V swing proportional solenoid valve 116-3526 1163526? | This flange-mounted rotary proportional valve fits E320B, E330B, E320C, E325B, E330C medium and large hydraulic excavators. |
| Q2 | How does this solenoid control excavator swing rotation speed? | It receives ECU PWM signal to generate proportional electromagnetic force, adjust the opening of swing control oil circuit, steplessly change the flow into swing motor to control rotary speed smoothly. |
| Q3 | What abnormal rotary faults will occur when this solenoid is damaged? | Unsmooth swing action, out-of-control rotation speed, slow rotary response, swing jitter during composite operation and continuous high hydraulic oil temperature. |
| Q4 | Is full disassembly of the multi-way valve required during replacement? | No, external flange fixed design, only remove four fixing bolts and disconnect the wire plug, no need to split the internal main valve body. |
| Q5 | What anti-wear and high-temperature design adapts to long-term mining work? | The whole spool undergoes ion nitriding hardening treatment, matched double high temperature HNBR sealing rings and fully sealed two-pin waterproof plug to resist hydraulic oil, dust and continuous high heat. |
| Q6 | Are 116-3526 and 1163526 interchangeable part numbers? | Yes, these two codes represent the same complete swing proportional solenoid assembly and can be replaced mutually. |
| Q7 | How to quickly detect coil damage before installation? | Use a multimeter to measure coil resistance, normal range 14–14.8 ohms; infinite resistance means open circuit, resistance below 10 ohms indicates internal short circuit and cannot be installed. |
