8pcs of DN200 pneumatic ceramic butterfly valve and 4pcs DN200 ceramic swing disc valve delivered to a well known steel manufactory in Russia.
Abrasion-resistant butterfly valve and swing disc valve.
The series D672G-10P Ceramic lined butterfly valve is the double-eccentric spherical sealing structure designed.The seat and sealing ring are made of ZrO2 which material is the abrasion-resistant and corrosion-resistant material.

Pneumatic ceramic swing disc valve
Application specification
Nominal Diameter:PN200-DN300 [Reduced bore]
Nominal pressure 1.0MPa 150Lb
Applicable media: dry ash, pulverized coal, materials and media containing particles, etc.
Temperature: ≤280°C
1. Corrosion Resistant:
Cold Isostactic Pressing (CIP) and high-temperature sintering nanometer high-purity 99% Al2O3 and 99.7% Al2O3 (alumina) and ZrO2 (zirconia) ceramics will not interact with almost all organic and inorganic chemicals, nor contaminate process medium. Their physically and chemically stability against most acids, salts and alkalis will last for many years with little or no corrosive degradation, which make sure that Floating Ceramic ball valve have excellent performance in corrosive applications.
2. Abrasion Resistant:
The hardness of 99% alumina ceramics is about HRA88, harder than zirconia (about HRA85), solid tungsten carbide is about HRA 90,which is about 8 times harder than stainless steel. As valve trim, ceramic components make Floating Ceramic ball valve work well in the most severe abrasive conditions, such as pneumatic conveying to transport silicon powder, coal powder, Mg powder, etc.
3. Ceramic-to-Ceramic spherical seated:
The perfect fine grinded spherical seal between ceramic ball and seat ensure a Class VI shutoff. The anti-scratch design between disc and seat, which prevent sealing surface from being scratched by particles. The ceramic ball will not be stuck so ball will not be broken.
Temperature range
Depends on the material used for Plug type ceramic check valves, the normal working temperature is -29~250 degree.
Valve tightness
The disc and seat sealing face are well polished, all the ceramic globe valve have tight shut off properties. The leakage class is up to Class VI.
