Use the original catalog dimensional reference and hydraulic symbol to compare the valve with the removed component and the machine schematic before purchase approval.
Complete every control point below before a sample or bulk order is released.
Approval Point | Buyer Review |
|---|---|
Reference | KWE5K-31/G24YB50 |
Electrical | 24V; 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 | Kobelco excavator hydraulic pump control using KWE5K-31/G24YB50 |
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 manifold bore shows possible wear, keep the verified reference, measurements and test result in the service record. Approve KWE5K-31/G24YB50-T from the complete old valve marking, 24v 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 new supplier lot enters dimensional inspection, 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 24V. 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 seal leakage complaint is assessed, keep the verified reference, measurements and test result in the service record. Use the drawing to compare overall length, thread or flange position, sealing diameters and connector clearance with the removed component. Read the spring side of the hydraulic symbol as the normal state and the solenoid side as the energized state. Port letters are catalog identifiers and must be reconciled with the equipment schematic before commissioning.
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 Kobelco 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 a workshop compares two connector orientations, keep the verified reference, measurements and test result in the service record. Fine debris can restrict the moving element, damage sealing lands or block a pilot passage even when the coil energizes normally. Review the equipment filtration requirement, inspect the removed valve for particles and flush the affected circuit when contamination is found. Replacing KWE5K-31/G24YB50-T without correcting dirty oil can reproduce slow response, sticking or repeated coil stress soon after installation.
During a hydraulic schematic differs from the catalog port letters, keep the verified reference, measurements and test result in the service record. The spring side of the circuit symbol defines what the machine does when electrical power is absent. That state can hold, unload, block or route pilot pressure, and the wrong choice may create movement or pump load at startup. Compare the original schematic with the catalog symbol and verify the safe normal condition before energizing the replacement in the machine.
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.
