DN80 Gate Valve

Description

Parameter / Process	Specification & Technical Highlights	Advantage / Value
Material	Grade 304 Stainless Steel (CF8 / 1.4301 equivalent)	Excellent general corrosion resistance and durability for versatile industrial pipeline media.
Valve Standards	DN80 / CL150 (Class 150)	Compliant with international flange and pressure rating standards for seamless pipeline integration.
Unit Weight	46.33 kg (Heavy-Duty Large Scale)	Demonstrates our advanced capability in handling heavy, large-scale precision investment casting.
Advanced Core Process	Water-Soluble Core Molding for wax mold pressing	Enables the creation of complex, seamless inner cavities with ultra-smooth fluid channels, minimizing pressure drop.
Tooling Design	Optimized mold structure	Reduces internal stress during casting and minimizes potential subsurface defects in thick-walled sections.
Casting Tolerance	ISO 8062 (GB/T6414) CT6 Grade	High near-net-shape accuracy, drastically reducing secondary CNC machining time on flanges and sealing faces.

To ensure long-term pressure containment and flawless structural integrity under industrial environments, we execute strict final inspections:

Water-Soluble Core Residue Check: 100% inspected to ensure the complex inner cavity is perfectly clean, clear, and free from any core residues.
Dimensional Integrity (CMM): Precision checking via Coordinate Measuring Machines to verify critical flange alignments, wall thicknesses, and sealing face concentricity against your CAD drawings.
Airtightness & Pressure Testing: High-pressure pneumatic/hydraulic testing is performed to ensure the heavy-duty body achieves a 100% leak-proof seal.
Material Verification: Validated by Spectrometers for precise chemical composition (Cr/Ni ratios) and tested for mechanical properties.
Non-Destructive Testing (NDT): Processed via Liquid Penetrant Testing (LPT) to guarantee a subsurface structure completely free of cracks or porosity.

Tailored Engineering: Fully customizable for various valve types (Globe Valves, Ball Valves, Gate Valves) and ratings (CL300, CL600) based on your 2D/3D blueprints (STEP, IGES, DWG).
Flexible Surface Treatments: Available with sandblasting, acid passivation (for enhanced corrosion layer), or tailored pickling finishes.
Complete Documentation: Full material mill test certificates (EN 10204 3.1) and CMM dimensional logs are provided with every delivery.
