| No. | Question | Standard Answer |
|---|---|---|
| Q1 | Which construction machine matches dual solenoid valve 223-8181? | This two-way directional solenoid assembly is exclusively designed for 420D backhoe loader auxiliary hydraulic valve block. |
| Q2 | What cross reference part number corresponds to 223-8181? | The interchangeable short OE code is 2238181, both codes represent the same double coil valve assembly. |
| Q3 | Do I need to adjust oil pipelines or cut wires during installation? | No modification required, mounting hole, hydraulic port and plug size fully comply with original factory standard. |
| Q4 | What common auxiliary action faults can this dual solenoid repair? | It solves slow forward/reverse auxiliary movement, weak output force and hydraulic leakage caused by damaged original valve. |
| Q5 | What structural advantage does double coil design bring? | Two independent coils realize rapid bidirectional oil flow switching, improve auxiliary operation response speed. |
| Q6 | What voltage does the internal double coil support? | Standard DC24V, matched with universal power supply system of backhoe loaders. |
| Q7 | Will frequent reciprocating switching cause oil leakage of the valve body? | Precision matched spool and multi-layer composite seals greatly reduce leakage risk after millions of switching cycles. |
| Q8 | Can I purchase a single piece sample to test fitting performance on my 420D machine? | Yes, single-piece sample order is supported for model matching and hydraulic performance inspection. |
