Tungsten Carbide Valve Gate

high performance valve gate

Valve Gate: The core parts of flat gate valves used in the petrochemical industry require high pressure, wear resistance, corrosion prevention against H2S and CO2, especially wellhead and Christmas tree valves have higher requirements.

Tungsten carbide is one of the most important raw materials for cemented carbide. It's a black hexagonal crystal with metallic luster, chemical stability, hardness and diamond similarity, and it's also a good conductor of electricity and heat. In tungsten carbide, carbon atoms are intercalated into the gap of the tungsten metal lattice without destroying the crystal lattice of the original metal, thereby forming a gap solid solution, and thus the tungsten carbide is also called an interstitial compound (or an intercalation compound). Tungsten carbide is suitable for machining at high temperatures-- it can make cutting tools, structural materials for kiln, jet engines, gas turbines, nozzles, etc.
