WC Tungsten Carbide Valve Seats / Tungsten Carbide Valve Core
Description
WC hard alloy valve core, the valve seat is made of YG11 (cobalt based) or YN11 (nickel based) cemented carbide + 17-4P duplex stainless steel. The product has high hardness, erosion resistance, corrosion resistance and high temperature resistance. Anti-high frequency vibration, no break, reliable connection and so on.
High strength, high wear resistance, high precision, high temperature resistant, corrosion resistant.
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.
They are used with compatible cemented carbide valve seats.
