| No. | Question | Answer |
|---|---|---|
| Q1 | Which excavators fit solenoid 121-1491 / 1211491 KWE5K-31/G24DB30? | Fits E320B/E320C/E320D/E325C rotary hydraulic control system with yellow square plug. |
| Q2 | Main function of this swing proportional solenoid? | Regulate swing flow and release rotary brake for smooth rotation; power off locks swing motor. |
| Q3 | Common faults caused by damaged valve? | Swing jitter, slow rotation, brake failure, intermittent action lag and high hydraulic oil temp. |
| Q4 | Need to disassemble multi-way valve during replacement? | No, flange bolt fixed, direct replace without splitting valve block. |
| Q5 | High temperature & wear resistant structure? | Ion nitriding spool, H-grade pure copper coil, double HNBR oil-proof sealing rings. |
| Q6 | Are 121-1491,1211491,KWE5K-31/G24DB30 interchangeable? | Yes, all three codes belong to one complete swing solenoid assembly. |
| Q7 | How to test coil before installation? | Measure resistance 14–15Ω; infinite resistance=open circuit, below 10Ω=short circuit. |
