SECO Electric ceramics o-type ball valve


    SECO Electric ceramics o-type ball valve,component by 3601R series angle travel electronic electric actuators and valve body.All contact with the media's part adopts zirconia ceramics, rockwell hardness HRA87 as aboveBesides with most advantages of metal ball valve. it also has strong corrosion resistance, temperature, abrasion and corrosion proof Characteristics,etc.Widely used in petrochemical, metallurgical, papermaking, power stations, refining industry of gases, liquids, acid and alkali salt mud and high temperature steam in the conveying system.And is strong corrosion situation titanium valve, monel valve ideal alternative.

   This series ceramic ball valve has advantages of low cost, high efficiency operation and long life,( 2 ~ 4 times of ti valve).

Its main application fields are as follows:
1 Power plants (desulphurizing installations, fly ash, lime and lime slurry, gypsum, filtrate etc.)
2 waste incineration (desulfurization, lime slurry, HCI absorption tower, etc.)
3 Steel plant(pulverized coal injection, steel mills and lime desulfurization MgO silicate, etc.),
4,Paper industry( kaolin rocks, talc, quartz off, and other paper MgO CaCO3, packing, bleach,  the filtrate NaOH,etc)
5. Chemical plant(acids, metal, organism, polymer, TiO2 grout, TiCI4, FeCI2, agent, mixture...).
6. Pneumatic conveying(lime, glass and cement, ore, gypsum, powder etc.)
7.Fertilizer (Nitric acid, phosphoric and melamine phosphate)
