Approval Point | Buyer Review |
|---|---|
Reference | KDRDE5K-31/30C50-143 / KDRDE5K-31/30C50-102 / 50120312-0498 |
Electrical | Confirm from removed valve; verify at the loaded connector during the actual command |
Mechanical | Compare flange mounted kawasaki cartridge, cartridge length, seals and installed clearance |
Hydraulic | Confirm normal state, energized state and manifold port relationship |
Machine Evidence | Sany and compatible excavator pump control using the exact Kawasaki valve marking |
Separate electrical command, cartridge movement and machine response so the actual wiring or hydraulic fault is not hidden by a parts replacement.
Observed Condition | Recommended Check |
|---|---|
No movement | Check loaded connector voltage, ground, controller command and coil resistance. |
Slow response | Inspect oil cleanliness, filter condition, viscosity and cartridge movement. |
Reversed response | Stop operation and compare normal and energized port logic with the original valve. |
External leakage | Inspect seals, cartridge surface, manifold bore and correct seating depth. |
Repeated heating | Confirm voltage, duty cycle, connector resistance and full magnetic movement. |
During a cross border quotation needs technical approval, keep the verified reference, measurements and test result in the service record. Approve KDRDE5K-31/30C50-143-T from the complete old valve marking, confirm from removed valve electrical version, connector keying, flange mounted kawasaki cartridge, sealing lands and normal hydraulic state. A shared equipment model does not prove interchangeability because pump and manifold revisions can change during production. Send the machine model, serial number and clear removed part photos with the inquiry.
During a controller output fault is suspected, keep the verified reference, measurements and test result in the service record. Read the coil label first and measure voltage at the connector while the real machine command is active. The working reference for this page is Confirm from removed valve. Do not infer voltage only from battery count because converters, harness changes and mixed voltage fleets can create misleading assumptions. Record the verified value on the purchase order and incoming inspection label.
During a first article sample is reviewed, keep the verified reference, measurements and test result in the service record. Verify commanded voltage under load, coil duty cycle, connector resistance and whether the hydraulic element reaches its intended position. Low voltage can prevent full magnetic pull, while excessive voltage or continuous energization can overheat the winding. Contamination that restricts cartridge movement can also increase operating stress, so correct the electrical or hydraulic root cause before fitting another coil.
During a cross border quotation needs technical approval, keep the verified reference, measurements and test result in the service record. Serial number evidence is essential whenever the same equipment family used more than one pump, manifold or electrical harness. Use it with the parts diagram rather than as a substitute for physical checks. If the old valve label is damaged, collect connector, mounting, cartridge and installed location photos so the application can be narrowed without guessing from the machine name alone.
During a controller output fault is suspected, keep the verified reference, measurements and test result in the service record. Compare the connector face, key position, pin count, latch direction and cable exit with the removed component. Also check whether suppression is built into the coil because this can affect controller diagnostics. Photograph the connector straight on beside a ruler and include the terminal condition in the RFQ, especially when several Sany harness revisions are used in the same fleet.
During cold start commissioning is completed, keep the verified reference, measurements and test result in the service record. A controlled sample review should confirm physical fit, connector engagement, coil current, leakage and the machine response in both normal and energized states. For this hydraulic pump solenoid valve, record warm oil behavior and response time as well as cold start operation. Retain the approved label photos and measurements so the production lot can be checked against the same acceptance record.
During contaminated hydraulic oil has been discovered, keep the verified reference, measurements and test result in the service record. Measure voltage across the coil while the controller commands the valve, then measure the positive and ground side drops separately. A static open circuit reading can look normal while a corroded terminal collapses under load. Compare the result with the confirmed confirm from removed valve requirement and repair excessive resistance before judging the hydraulic pump solenoid valve itself as defective.
Send the complete old valve marking, confirmed voltage, machine model and serial number, connector photos, interface dimensions and required quantity for a fitment focused B2B quotation.
