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 | Use complete old-valve evidence |
Electrical | 12V; verify at the loaded connector |
Mechanical | Compare 3/4-16 unf-2a, sealing positions and installed clearance |
Hydraulic | Confirm normal state, energized state and port relationship |
Machine Evidence | Hydraulic pilot circuits using the matching 3/4-16 cartridge, connector and normally closed two way logic |
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 a first article sample is approved, keep the verified measurements and test result in the service record. Use the complete old marking, 12v electrical version, connector face, 3/4-16 unf-2a, 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 repeat overheating case is investigated, 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 a connector cavity shows corrosion, keep the verified measurements and test result in the service record. Treat 220 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 return analysis starts without machine records, 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 3/4-16 unf-2a, 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 warm hydraulic system develops slow response, keep the verified measurements and test result in the service record. Measure supply and ground at the loaded connector, then check coil resistance and verify that the controller issues the command. If electrical input is correct, inspect oil cleanliness, filter condition, moving-element freedom and manifold contamination. Separate electrical command from hydraulic response before replacing another valve so a harness or blocked pilot passage is not missed.
When a serial-controlled overhaul is planned, keep the verified measurements and test result in the service record. 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. Reconcile catalog port letters with the equipment schematic before commissioning because labels can differ between valve and machine drawings.
When a fleet contains two similar coil versions, keep the verified measurements and test result in the service record. Provide the complete old label, machine model and serial number, confirmed voltage, connector face, cartridge or flange measurements, hydraulic function, required quantity and destination. Separate every suffix or electrical version on the inquiry. This evidence allows technical matching and sample approval to proceed with the commercial quotation instead of through repeated clarification.
Send the complete old marking or component evidence, confirmed voltage, machine information, clear photos, measurements and required quantity for a fitment-focused B2B quotation.
