Precision hydraulic valve body spool CNC machining parts

1.Core Functions

• Flow Control：Regulates hydraulic oil flow by axial movement to adjust orifice opening.

• Pressure Regulation：Works with valve body to manage pressure via relief, reduction, etc.

2. Key Details

• Material：

  • Alloy steel with quenching/carburizing, hardness HRC58-62.

  • Stainless steel for corrosive environments.

• Dimensional tolerance ±0.001mm, surface roughness Ra≤0.2μm.

• Chromium/Ni-P plating for anti-friction & corrosion resistance.

3.Core Roles

• System Efficiency：Minimizes internal leakage, improves system responsiveness.

•  Stability：Withstands high pressure (35MPa+) and temperature swings.

• Lifespan：Optimized clearance ensures millions of cycles.

4. Key Advantages

• Precision：CNC grinding + superfinishing for extreme conditions.

• Customization：Tailored dimensions, materials, and coatings.

• Reliability：Rigorous QC: pressure testing, roundness inspection, etc.
