Use the original catalog dimensional reference and hydraulic symbol to compare the valve with the removed component and machine schematic before purchase approval.
Complete every control point below before a sample or bulk order is released.
Approval Point | Buyer Review |
|---|---|
Reference | KDRDE5K-50/30C50-122 |
Electrical | 12V; verify at the loaded connector |
Mechanical | Compare flange mounted kawasaki valve body, sealing positions and installed clearance |
Hydraulic | Confirm normal state, energized state and port relationship |
Machine Evidence | Kobelco SK75-8, SK130-8, SK200-8, SK250-8, SK260-8, SK330-8 and SK350-8 pump control with full model confirmation |
Separate electrical command, component movement and final machine response so the actual wiring or hydraulic fault is not hidden by 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 valve movement. |
Reversed response | Stop operation and compare normal and energized port logic. |
External leakage | Inspect seals, valve surface, bore condition and seating depth. |
Repeated heating | Confirm voltage, duty cycle, connector resistance and full movement. |
When cold-start commissioning is completed, keep the verified measurements and test result in the service record. Use the complete old marking, 12v electrical version, connector face, flange mounted kawasaki valve body, sealing positions and the machine hydraulic schematic. A reference alone cannot prove that the normal and energized flow paths match. Record the machine model, serial number and removed-valve photographs with the approved sample so repeat orders follow the same engineering basis.
When a remote service kit is prepared, keep the verified measurements and test result in the service record. Read the voltage marking on the removed coil and measure supply at the loaded connector while the controller commands the valve. Do not infer voltage only from battery count because converters, harness changes and mixed fleets can produce another coil supply. Keep the confirmed value on the inquiry, purchase order, carton label and incoming inspection record.
When warehouse stock must remain voltage-separated, keep the verified measurements and test result in the service record. Treat 41 bar as a component reference that must remain within the actual circuit requirement, not as permission to ignore the machine service data. Confirm which ports see pressure in both switching states, review return pressure and verify the cavity or flange. Pressure capability cannot correct a wrong spool function, cartridge depth or manifold relationship.
When a mixed-voltage shipment reaches receiving inspection, keep the verified measurements and test result in the service record. Two valves can share a coil diameter and connector while using different cartridge lengths, sealing lands, spring forces or port logic. Compare flange mounted kawasaki valve body, overall length, installed depth, connector direction and hydraulic symbol. A part that mounts correctly but routes pressure differently can create weak response, reversed movement or continuous pump loading.
When a fleet contains two similar coil versions, keep the verified 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 movement can add operating stress, so correct the electrical or hydraulic cause before installing another unit.
When a technician checks current draw under load, keep the verified measurements and test result in the service record. Check the complete reference and voltage against the purchase order, then sample connector keying, overall length, mounting interface, seal count and coil resistance. Keep voltage and suffix variants physically separated. For the first lot, compare one unit with the approved old component before releasing the remaining quantity to warehouse stock or field service.
When a distributor prepares repeat stock, keep the verified measurements and test result in the service record. Serial evidence is essential whenever one equipment family used more than one pump, manifold or harness revision. Use it with the parts diagram rather than as a substitute for physical checks. If the old label is damaged, collect connector, mounting, cartridge and installed-location photographs so the application can be narrowed without guessing from the machine name.
Send the complete old marking or component evidence, confirmed voltage, machine information, clear photos, measurements and required quantity for a fitment-focused B2B quotation.
