How do I choose the correct excavator proportional solenoid valve?
Short Answer
Choose the correct excavator proportional solenoid valve by matching the machine serial number, valve location, coil voltage, connector shape, resistance value, spool type, hydraulic function, and any code stamped on the old valve. JIAJUE checks both electrical and hydraulic details because two proportional valves can share the same connector but control different pump, travel, swing, or attachment functions.
What To Check
- Send photos of the old solenoid, connector, valve block position, part number, coil marking, and the full pump or valve assembly.
- Measure coil voltage and resistance if possible, and confirm whether the fault code points to open circuit, short circuit, low current, or abnormal pressure control.
- Check harness damage, controller output, oil contamination, sticking spool, and whether swapping valves moves the fault before ordering.
