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.
