YFL Ceramic O-port ball valves  are suitable for corrosive  fluid and abrasive solid duo to the excellent corrosion and abrasion resistance of ceramic. They are use widely in corrosive and abrasive  applications as follow:

1. Copper powder, concentrated copper slurry, nickel slurry  in Mining
2. Ash, lime slurry and gypsum slurry in flue gas desulphurisation (FGD) system in coal fired power plant
3. All types of dry bulk materials like quartz, fiber, ash glass and PP pellet in pneumatic conveying system
4. Limestone, ore, coke, dust, coal powder injection, carbon powder injection, additives like CaC, MgO2 in Iron & Steel
5. Dolomite, Ammonium nitrate slurry, Phosphoric acid with solids in Fertilizer industry
6. Aluminium oxide powder as catalyst, pigments( TiO2 suspension, Ti3Cl4, H2SO4+TiO2, FeCl2 etc.) in Petrochemical industry
7. Kaoflin, bentonite, fillers, dyes, pulp residue, lime suspension, MgO2, green liquor, wood particles in Paper industry
8. Silicon powder in Polysilicon industry
9. Alumina powder in Alumina plant
10. Cement in cement plant

For any other severe applications, please feel free to contact YFL engineers for best solutions.

YFL Ceramic O-Port Ball Valves Features:

• All wet parts in material of ceramic
