Tungsten Alloy Valve Balls – High-Performance Sealing Solution

Why Tungsten Alloy?

Tungsten carbide (WC) or heavy alloy (WNiFe/WCu) valve balls outperform steel, ceramic, and plastic in extreme conditions due to:

Ultra-High Hardness (HRA 90+) – Resists abrasive slurries, scaling, and particle erosion.

Corrosion Resistance – Withstands acids, alkalis, and seawater (pH 1–14).

Density (14–15 g/cm³) – Improves shut-off pressure ratings (ANSI Class VI sealing).

Thermal Stability (-200°C to +600°C) – No deformation in cryogenic or high-temp processes.
