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/G24DB50-KY / YN35V00050F1 |
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 the exact Kawasaki valve model |
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 an emergency field repair is evaluated, keep the verified reference, measurements and test result in the service record. Approve KWE5K-31/G24DB50-KY 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 machine returns after long storage, 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. 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 hydraulic schematic differs from the catalog port letters, keep the verified reference, measurements and test result in the service record. Check the printed reference and voltage against the purchase order, then sample connector keying, overall length, mounting interface, seal count and coil resistance. Keep voltage or suffix variants physically separated and traceable. For the first production lot, compare one unit with the approved old component before releasing the remaining quantity to warehouse stock or field service.
During a mixed voltage shipment reaches receiving inspection, 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/G24DB50-KY without correcting dirty oil can reproduce slow response, sticking or repeated coil stress soon after installation.
During a workshop compares two connector orientations, 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.
During a pilot passage blockage is investigated, keep the verified reference, measurements and test result in the service record. Keep ports capped, seals protected and connector faces free from moisture or impact. Separate 24v and suffix variants with readable carton labels so warehouse picking cannot mix them. Store the valves in a clean, dry area away from welding dust and corrosive chemicals, and retain lot traceability to the approved sample and incoming inspection record.
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.
