Valve balls/seats/core are specifically developed to resist wear at high temperatures. The material is based on wear-resistant carbides that are thermally stable at exhaust valve seat operating temperature. They are mainly used for the sealing of valves of oil pumps in petroleum industry's sand containing wells,viscous oil wells,sea oil wells and high pressure sulfur resistant oil wells,etc. We can manufacture depend on customers’ requirement.

Tungsten carbide balls are widely used in the manufacture of ball bearings due to their extremely high hardness and wear resistance.

Tungsten carbide balls are made by powder metallurgy using tungsten carbide (WC) powder and metal binders such as cobalt (Co) and nickel (Ni). Common grades include YG6, YG8, YN6, YN9, etc. We can customize products according to our needs.
