Ultra-Precise 0.004mm Mating Clearance & High-End Machining Pathways
- Sub-Micron Mated Clearance: The valve core and sleeve are precision-ground as an interlocking matched set, achieving an ultra-tight clearance fit of 0.004mm to secure internal pressure fluid seals and eliminate oil bypass.
- Internal & External Cylindrical Grinding: Both the outer diameter of the spool core and the functional seating faces of the outer sleeve are micro-ground to ensure total concentricity, true roundness, and parallel alignment.
- Advanced Honing & Centerless Grinding: Internal sleeve bores undergo high-accuracy honing, while the piston rods are centerless-ground to establish a flawless mirror finish that eliminates frictional drag and micro-sticking.
Comprehensive Parameter Customization & Drawing-Based OEM Flexibility
- Fully Tailored to Your Blueprints: We offer complete OEM/ODM manufacturing flexibility, delivering high-precision valve cores and sleeves processed exactly to your provided 2D drawings (PDF/DXF) or 3D CAD files (STEP/IGS).
- Custom Dynamic Operating Metrics: We excel at adjusting key structural parameters directly to your fluid network requirements, allowing custom configurations for port connection diameters, nominal pressure tolerances, oil-box operational capacities, and rated flow capacities.
- Premium Hardened Metallurgy: Fabricated from industrial tool and bearing steels (such as SUJ2, SKD11, or SUS440C) and vacuum heat-treated to maximize surface hardness, preventing score marks from fine fluid contaminants.
