Valve model issue

What does WC mean in DN80-Q41WC-16C-RF? Is it a typo{:3_46:}
4 indicates the connection method: flange. 1 indicates a straight-through flow channel. F indicates that the material of the valve sealing pair is fluoroplastic. 16 indicates that the nominal pressure of the valve is PN16. C indicates that the valve body material is carbon steel; DN80 denotes that the nominal size of the valve is 80, with 80 being directly related to the bore diameter; RF indicates that the sealing surface type for flange connections is a raised face. Q denotes a ball valve. wc —— W stands for welding, C stands for casting
The sealing pair is made of a super-wear-resistant tungsten carbide alloy produced by supersonic flame spraying
WC stands for tungsten carbide; it can only be applied by spraying to increase surface hardness and wear resistance. However, it is not commonly used in valves, but rather in shafts and valve stems. It is not suitable for use on sealing surfaces as it tends to fall off easily
Thank you all {:3_48:}
