Tungsten carbide is an important raw material in valve parts. Valve seat is wearing part. The important point is: it in the pipe. The medium will crushing the inner place. If the valve seat were not maintained properly, it would get rusty as time passes. Tungsten carbide features: High hardness, corrosion and wear resistance etc. It's high hardness and wear resistance to ensure valve seat guarantee quality. The advantage is tungsten carbide is washing-out resistance. When the liquid into valve, it will washing-out valve seat. The raw material is more important. When parts or machine rubbing against each other, we always using tungsten carbide for valve seat raw material. This way is most quickly, easily way to solve work piece corrosion problem. It's versatility and flexibility in various work piece. It's mainly used in Oil, Gas industry and so on. After accurate grinding and polishing, the frictional factor of surface is very low. We accept customized service. If you have other specification, you can contact us.Zonco is your partner in Tungsten carbide industry. For tungsten carbide material grade, we suggest: YG8, YG11, YG15, YL10.2, YN8 other grade can be offered by customers' request.
