Product Description

Wear-Resistance Tungsten Carbide Custom Valve Core and Seat
Under extreme working conditions involving high temperature, high pressure, high erosion, and strong corrosion, traditional metal sealing pairs often fail due to insufficient hardness or corrosion resistance. Our Tungsten Carbide Custom Valve Core and Seat, manufactured using high-quality virgin tungsten carbide powder and advanced powder metallurgy/thermal spray processes combined with precision grinding technology, provide you with the "hard sealing" core component for extended service life.
Core Product Advantages
  • Extreme Hardness, Fearless of Wear: Tungsten Carbide (WC) material achieves a hardness of HRA 89-93, second only to diamond, effectively resisting particle erosion in high-velocity media.
  • Corrosion Resistance & High-Temperature Stability: Offers stable chemical properties, resisting most acids, alkalis, and corrosive media, while maintaining excellent red hardness suitable for high-temperature steam and thermal oil applications.
  • Mirror-Finish Lapping, Zero Leakage: Utilizing high-precision grinders and lapping processes, the sealing surfaces achieve a mirror finish, ensuring bubble-tight sealing under hard sealing conditions (ANSI Class VI).
  • Customizable to Drawing, Flexible Matching: We accept custom orders based on customer-provided drawings, operating parameters, or reverse engineering of old parts, supporting non-standard angles, non-standard flow paths, and special structures.

Customization Process
  1. Requirement Communication: Customer provides operating parameters (medium, temperature, pressure) and installation dimensions.
  2. Drawing Confirmation: Customer provides existing drawings, or our technical department performs free reverse engineering to create 3D/2D drawings.
  3. Material Selection: Recommend the most suitable tungsten carbide grade based on operating conditions (e.g., YG6X for high wear resistance, YG15 for impact resistance).
  4. Precision Machining:
    • Pressing/Sintering: Forming the blank
    • Rough Grinding: Machining flow paths and external shapes
    • Fine Grinding & Lapping: Ensuring 100% contact and zero gap between the core and seat
  5. Quality Inspection: Hardness testing, flaw detection, and gas tightness testing.
  6. Delivery & Use: Packaging, shipping, and providing material certificates and inspection reports.
Typical Applications
  • Petrochemical Industry: Catalytic cracking units, high-temperature oil slurry valves, polysilicon valves
  • Power Generation: Ash handling systems, slag discharge systems, desulfurization and denitrification valves
  • Mining & Metallurgy: Slurry pipelines, wear-resistant slag discharge valves, coal chemical lock hopper valves
  • General Industry: High-pressure shower systems in paper industry, powder conveying valves in food industry
