XCMG 55-Ton Crane Solenoid Valve Assembly 80300259

Part number 80300259 is listed as a solenoid valve assembly for selected XCMG 55-ton crane hydraulic applications. The electrical coil operates a hydraulic valve function, so both the electrical and hydraulic configuration must match the original assembly.

Identification Checklist

• Part number 80300259 and all supplier markings

• XCMG crane model and complete serial number

• Valve-block assembly reference and installed cavity position

• Coil voltage shown on the label

• Connector style, pin count and keying

• Valve body, port or cartridge geometry and seal positions

Application and Service Scenarios

This assembly is relevant when a confirmed electrical or hydraulic fault prevents the associated crane function from switching correctly, or when the valve is damaged during valve-block service. Typical investigation may begin with an inactive function, intermittent response or a diagnostic fault, but those symptoms do not prove that the complete valve assembly is defective.

Diagnosis Before Replacement

Check the control signal, supply voltage, coil resistance, connector terminals, harness condition and ground circuit. Inspect the hydraulic system for contamination, restricted pilot supply or a mechanically stuck spool. A good coil cannot correct a contaminated valve, and a new valve will not solve missing electrical command.

Fitment and Installation

Depressurize and clean the hydraulic area according to the machine procedure. Record orientation and seal placement before removal. Do not substitute a coil or valve with an unconfirmed voltage, connector or hydraulic function. Torque, test pressure and commissioning should follow the applicable service data.

Clean Export Packing

Hydraulic openings are capped, seals are protected and the coil connector is cushioned against impact. Anti-static protection is used where appropriate, and the package label shows 80300259 and the confirmed application.

Frequently Asked Questions

Does part number 80300259 confirm the entire assembly?

It is the primary reference, but coil label, connector, valve body and machine information should still be compared.

Can a failed crane function prove the solenoid valve is faulty?

No. Wiring, controller output, pilot pressure, contamination and mechanical conditions can create similar symptoms.

Can a coil with the same size be substituted?

Only when voltage, connector, power and valve compatibility are confirmed.
