YFL PN10 DN80 Ceramic V-Port ball valves were exported to food company in Spain for abrasive and corrosive cocoa powder. The existing valves which our client used in have abrasion and corrosion problems. The detailed working conditions and requirements from our client are as follows:

1. medium:  carbonate steam with cocoa powder, the medium is corrosive and abrasive.

2. working pressure: 2bar

3. working temperature: 150℃

4. Operation method: pneumatic actuated

5. On/Off or Regulating: Regulating

Considering there is steam in the medium, we customize our ceramic ball valves with ball in material of Alumina (Al2O3) instead of Zirconia (ZrO2), and the seat is made of Alumina (Al2O3). Normally for ceramic ball valves, Zirconia (ZrO2) is more suitable than Alumina (Al2O3) to be material of ceramic ball duo to higher flexual strength. But Zirconia (ZrO2) can't be used when there is steam in the medium. And the ceramic ball has a V-notch to achieve precise regulating performance.

With the extreme hardness and excellent physical and chemical stability, the ceramic materials are abrasion resistant and corrosion resistant against almost all abrasive solid and corrosive fluid.

YFL ceramic ball valves will solve abrasion and corrosion problems, reduce maintenance cost and create values for our clients.
