Applications:

Since ceramics material have high hardness and excellent strength, FUVALVE developed Ceramic Y Diverters, which are widely used in most of the high corrosive and abrasive transmission systems especially for coal fired power plants, steel plants, mining, الصناعة الكيميائية, petro-chemical, البولي سيليكون and metallurgy.

The following listed are some typical medium in which Ceramic Lined Y Diverters have been proved to have good performance.

Coal powder

Silicon powder

Fly ash

Mining slurry

Mining Slag

Coal washing

Strong acid slurry

Paper making Slurry
