Komatsu PC360-8 Multi-Way Valve – Excavator Hydraulic Distributor Main Control Valve

Product Features

• CLSS Load Sensing Control: Delivers precise, proportional flow to each actuator while reducing pump output at standby for fuel savings.

• Precision Flow Distribution: Smooth control for boom, arm, bucket, swing, and travel circuits.

• High-Strength Cast Body: Heavy-duty valve body withstands high pressure, vibration, and continuous duty cycles.

• Precision-Matched Spools: Each spool is selectively fitted to its bore for minimal internal leakage and consistent response.

• Integrated Relief Valves: Main relief and circuit relief valves protect the system from overload and shock pressure.

• Modular Sections: Individual sections can be serviced or replaced without replacing the entire valve.

• Low Pressure Loss: Optimized internal passages reduce energy loss and improve machine response.

Product Technology

This PC360-8 multi-way valve is manufactured using advanced casting, CNC machining, and precision honing. Valve bores are diamond-honed to micron-level tolerances, and spools are ground and matched for optimal fit. Critical surfaces are heat-treated for wear resistance. Every valve is assembled in a clean environment, pressure-tested, and flow-tested to verify performance before shipment.

Product Applications

• Komatsu PC360-8 Excavator: Direct replacement for the OEM main control valve.

• 36-Ton Excavator Fleets: Ideal for construction, quarry, and heavy earthmoving.

• Mining & Quarry: Reliable flow distribution under continuous heavy loads.

• Demolition & Attachment Work: Supports breakers, shears, and grapples with stable hydraulic supply.

• Repair & Rebuild Shops: Perfect for rebuilding PC360-8 hydraulic systems.

• Rental Fleets: Reduce downtime by keeping complete valves or sections in stock.

Manufacturing Process

1. Raw Material Inspection: High-grade cast iron and alloy steel are spectrographically tested.

2. Casting: Valve body is cast and heat-treated for strength and dimensional stability.

3. CNC Machining: Mating surfaces, bores, and ports are machined to micron-level tolerances.

4. Honing: Valve bores are diamond-honed for precise fit and low leakage.

5. Spool Grinding: Spools are ground and matched to their bores.

6. Heat Treatment: Critical surfaces are hardened for wear resistance.

7. Cleanroom Assembly: Components are assembled in a dust-free environment.

8. Pressure & Flow Testing: Each valve is tested for pressure holding, flow, and leakage.

9. Painting & Packaging: Anti-corrosion paint applied, packed in a wooden crate for export.

FAQ

Q1: How do I confirm this valve fits my Komatsu PC360-8?
This multi-way valve is designed for the Komatsu PC360-8. Please confirm your machine model, serial number, and original valve part number. Send us photos of your old valve’s data plate, and our team will confirm compatibility before you order.

Q2: Is this a genuine Komatsu part?
This is a high-quality aftermarket replacement manufactured to OEM specifications. It is not a genuine Komatsu part, but it matches OEM fit and performance at a significantly lower price.

Q3: What are the signs of a failing multi-way valve?
Common symptoms include weak or slow functions, drift, overheating, abnormal noise, and uneven cylinder movement. If you notice these signs, test system pressure and inspect the valve promptly.

Q4: Can I install this valve myself?
Installation requires hydraulic experience and proper tools. You must release system pressure, disconnect hoses and pilot lines, remove the old valve, and install the new one. Always flush the system and replace filters before startup. Video call support is available 24/7.

Q5: Do I need to adjust pressure settings after installation?
Yes. Main relief, LS pressure differential, and circuit relief settings should be checked and adjusted to Komatsu specifications after installation. Incorrect settings can cause poor performance or damage.

Q6: Do you provide seal kits and spare parts?
Yes. We stock seal kits, spools, relief valves, and solenoid components for PC360-8 valves.

Q7: How should I store a spare valve?
Store in a dry, clean area away from moisture and dust. Keep it in its original packaging until installation. Cap all ports to prevent contamination.
