Cemented Carbide Valve Balls are precision-engineered components crafted from tungsten carbide (WC-Co), renowned for their exceptional hardness, wear resistance, and durability in extreme operational environments. Designed for high-performance valve systems, these balls ensure reliable sealing, longevity, and resistance to corrosive media, making them ideal for critical applications in oil and gas, chemical processing, and industrial machinery.
주요 기능:
– Ultra-High Hardness: Composed of tungsten carbide with a cobalt binder (6%–12% Co), these balls achieve a Vickers hardness of up to 1600–1800 HV, ensuring resistance to abrasion, deformation, and mechanical wear.
– Corrosion & Chemical Resistance: Withstands aggressive environments, including acidic, alkaline, and high-salinity conditions, making them suitable for petrochemical and marine applications.
– High-Temperature Stability: Maintains structural integrity and dimensional accuracy at temperatures up to 600°C, ideal for high-heat processes such as steam valves or refinery systems.
– Precision Engineering: Tight sphericity tolerance (±0.005mm) and surface finish (Ra ≤ 0.2μm) ensure leak-proof sealing and smooth operation in valve assemblies.
– Long Service Life: Outperforms traditional steel or ceramic balls, reducing downtime and replacement frequency in demanding industrial settings.
Applications:
– Oil & Gas: Used in ball valves, choke valves, and downhole tools for drilling, extraction, and pipeline systems.
– Chemical Processing: Ideal for controlling corrosive fluids in reactors, pumps, and metering systems.
– Power Generation: Employed in steam turbine valves and high-pressure hydraulic systems.
– Aerospace & Automotive: Critical for fuel injection systems, hydraulic controls, and precision fluid handling.
Advantages:
– Cost Efficiency: Extended lifespan reduces maintenance costs and operational interruptions.
– Versatility: Compatible with a wide range of media, including abrasive slurries, hydrocarbons, and high-purity chemicals.
– Customization: Available in diameters from 1mm to 50mm, with options for tailored cobalt content, surface coatings (e.g., TiN, AlCrN), or specialized geometries.
– Sustainability: Durable design minimizes material waste and supports eco-friendly industrial practices.
Technical Specifications:
– Material: Tungsten Carbide (WC) with Cobalt (Co) binder (6%–12% Co).
– Hardness: HRA 89–94 (equivalent to HRC 70+).
– Temperature Resistance: Up to 600°C.
– Standards Compliance: ISO 9001-certified manufacturing with full traceability.
