206-60-51130 206-60-51131 Solenoid Valve for Komatsu 6D102 Engine PC200-6 Excavator

Product Overview

The 206-60-51130 / 206-60-51131 / 206-60-51132 solenoid valve is used for Komatsu excavator hydraulic control system applications. It is commonly referenced for PC200-6 machines with 6D102 engine applications.

This valve may also be described as a rotary solenoid valve or hydraulic solenoid valve in supplier listings. Final fitment should be checked by the original valve marking, connector type, voltage, mounting style and machine serial number before ordering.

Part Number and Cross Reference

Common reference numbers include 206-60-51130, 206-60-51131 and 206-60-51132. Non-hyphen formats may include 2066051130, 2066051131 and 2066051132.

These numbers should be treated as reference information only. Solenoid valves with similar numbers may still differ in connector shape, voltage, valve body marking, mounting position or hydraulic control application.

Application and Fitment Reference

Main references include Komatsu PC200-6 and 6D102 engine applications. Public supplier references may also list PC210-6, PC220-6, PC230-6 and PC300-6.

The model list should be used as a fitment reference, not a universal guarantee. Before purchase, compare the old valve body marking, connector type, wiring plug, mounting position, voltage and machine serial number.

Common Failure Symptoms

• Slow hydraulic response: boom, arm, bucket, swing or travel operation may respond slowly.

• Unstable machine movement: hydraulic response may change unexpectedly under load.

• Intermittent operation: valve response may become unstable after vibration, heat or connector movement.

• Electrical fault symptoms: loose pins, damaged wiring, poor ground or low voltage may imitate solenoid valve failure.

• Oil contamination: dirty hydraulic oil may restrict valve movement or cause sticking.

Troubleshooting Before Replacement

• Check the original valve marking and connector type before ordering a replacement.

• Inspect the connector for oil contamination, corrosion, loose pins or damaged locking tabs.

• Check wiring harness condition, ground connection and power supply.

• Inspect hydraulic oil condition and replace filters if contamination is present.

• Confirm whether the issue is caused by the solenoid valve, pump control circuit, wiring or hydraulic contamination.

Installation and Maintenance Notes

• Stop the engine and release hydraulic pressure before removal.

• Disconnect electrical power before unplugging the solenoid connector.

• Clean the valve mounting area to prevent contamination from entering the hydraulic system.

• Do not pull the wire harness directly; release the connector lock first.

• Install the valve carefully and confirm the connector is fully locked.

• After installation, check for leakage, warning symptoms and stable hydraulic response under light-load operation.

Fitment Check Before Ordering

To reduce wrong orders, please send the machine model, machine serial number, old valve marking, connector photo, mounting photo and full valve body photo before quotation.

FAQ

Q: What is the relationship between 206-60-51130, 206-60-51131 and 206-60-51132?

These numbers are commonly listed together as reference numbers for Komatsu 6D102 excavator solenoid valve applications. Final confirmation should be made by the old valve marking and connector.

Q: Which Komatsu models are commonly listed for this valve?

Common references include PC200-6, PC210-6, PC220-6, PC230-6 and PC300-6. Final fitment should be verified by the old valve and machine serial number.

Q: Is this valve related to the 6D102 engine?

Yes. Public listings commonly associate this solenoid valve with Komatsu 6D102 engine applications.

Q: What should be checked before ordering?

Check the valve body marking, connector type, voltage, wiring plug, mounting style and machine serial number. Clear photos of the old valve are recommended.

Q: Can electrical problems look like solenoid valve failure?

Yes. Loose connector pins, damaged wiring, poor grounding, low voltage or oil contamination can cause symptoms similar to a failed solenoid valve.
