328-4314 is a 24V pilot operated hydraulic solenoid valve for Caterpillar equipment using 328-4314 with confirmed valve function and serial range. Buyers should confirm the complete old marking, electrical version, connector, 1-1/16-12 cartridge shown and hydraulic function before approving replacement stock.

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 | 328-4314 |
Electrical | 24V; verify at the loaded connector during the actual command |
Mechanical | Compare 1-1/16-12 cartridge shown, cartridge length, seals and installed clearance |
Hydraulic | Confirm normal state, energized state and manifold port relationship |
Machine Evidence | Caterpillar equipment using 328-4314 with confirmed valve function and serial range |
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 incoming production lot is released, keep the verified reference, measurements and test result in the service record. Approve 328-4314 from the complete old valve marking, 24v electrical version, connector keying, 1-1/16-12 cartridge shown, 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 cross border quotation needs technical approval, 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 service kit is packed for remote repair, keep the verified reference, measurements and test result in the service record. Two valves can share a coil diameter and connector yet use different cartridge lengths, metering notches, spring forces or port logic. In Caterpillar service, compare the full reference, manifold bore, installed depth, connector direction and hydraulic symbol. A valve that screws in but routes pressure differently can create weak response, reversed motion or continuous pump loading.
During a pump control fault appears only under load, 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 connector harness revision is compared, 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 controller output fault is suspected, keep the verified reference, measurements and test result in the service record. Reuse is not recommended when the service procedure specifies new seals or the old rings show flattening, cuts or heat damage. Confirm material compatibility with the hydraulic oil, clean the 1-1/16-12 cartridge shown and inspect the manifold bore for scoring. Lubricate and install seals without twisting, then follow the equipment torque procedure instead of forcing the cartridge past resistance.
During cold start commissioning is completed, 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 328-4314 without correcting dirty oil can reproduce slow response, sticking or repeated coil stress soon after installation.
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.
