Product details

Here is the English translation of the content regarding theKomatsu Pressure Reducing Valve Assembly:

------

I. Product Function

1. Pressure Regulation:

• Reduces high hydraulic system pressure to a preset value, ensuring downstream components (e.g., cylinders, motors) operate within safe pressure limits.

2. Stable Output:

• Automatically compensates for pressure fluctuations via valve spool or diaphragm structures to maintain consistent outlet pressure, preventing equipment damage from pressure surges.

3. System Protection:

• Prevents hydraulic system overload, reducing risks of leaks, component wear, or hose bursts caused by abnormal pressure.

II. Technical Features

1. High-Precision Control:

• Adopts proportional or pilot-operated designs for sensitive pressure regulation, with typical tolerance ranges within ±2%.

2. High-Pressure Resistance:

• Valve bodies constructed from high-strength cast steel or ductile iron, with pressure ratings exceeding 35 MPa to withstand heavy-duty operations.

3. Reliable Sealing:

• Uses NBR (Nitrile Butadiene Rubber) or FKM (Fluorocarbon Rubber) seals to ensure long-term sealing performance under high-pressure oil conditions.

4. Modular Design:

• Supports quick replacement of valve spools or springs on certain models, facilitating field maintenance and minimizing downtime.

III. Applications

1. Hydraulic Systems in Excavators:

• Model Compatibility: Used in models like PC60-7, PC120-6, and PC200-6 to control pressure in boom, arm, and bucket cylinders.

• Functional Example: In the PC200-6, the valve ensures stable pressure during high-pressure startup of the swing motor, preventing impact damage.

2. Hydraulic Circuits in Bulldozers:

• Load-Sensing Control: Adjusts pump output pressure to match load demands in different working conditions (e.g., grading, dozing).

3. Loader Work Attachments:

• Boom/Bucket Priority Control: Coordinates cylinder pressures during combined movements to ensure smooth operation.

IV. Selection Parameters

1. Pressure Range:

• Common models regulate pressures from 0.5 to 31.5 MPa, with high-pressure variants reaching up to 35 MPa.

2. Flow Capacity:

• Flow ratings typically range from 20 to 200 L/min; match to hydraulic system flow requirements.

3. Port Specifications:

• Threaded ports (e.g., G1/2, G3/4) or flange connections (e.g., SAE 4-bolt flange) must align with piping systems.

4. Environmental Adaptability:

• Operating temperature range: -20°C to +80°C; some models support -40°C for cold climates.

V. Maintenance Recommendations

1. Regular Inspections:

• Check seals for aging every 500 hours; test pressure regulation accuracy every 2,000 hours.

2. Troubleshooting:

• Pressure Fluctuations: Inspect for spring fatigue or spool binding; replace spool assemblies if needed.

• Leakage: Replace O-rings or gaskets, ensuring valve body mating surfaces are free of scratches.

3. Maintenance Intervals:

• Recommended hydraulic oil change cycle: 2,000 hours; use oil with cleanliness class NAS 6 or higher.
