The YFL three
pieces forged body ceramic ball valve is
suitable for harsh applications as follows:
Coal
fired power plants: Flue gas desulphurisation plants (FGD); Lime
slurry and gypsum slurry process water with high chlorides and solids content;
Steel
works: Injection of coal powder (PCI); Injection of carbon powder in electric arc
furnaces (EAF); Raw iron desulphurisation (supply of additives: CaC, MgO2…)
Polysililcon:Si3Cl4,
TCS, raw silicon, splitting of silicon with acids, conveying of silicon powder;
