Ceramic ball valve

Advantages of structural ceramic ball valves include hi-economy, long life (2~4 times of Titanium Valves), increase resistance to corrosion, high temperature, wear and erosion etc.. They are commonly used in transportation systems of various acid, alkaline or saline gases, solutions, high working temperature steams and slurries, in the lines of oil industry, metallurgy, papermaking, power station, refinery, etc. Structural ceramic ball valves are the ideal substitute for titanium and monel valves in corrosive environments. There are four types of driving performances, manual, pneumatic, pneumatic-spring return and electric. Various special valves can be designed on demand. Furthermore, various high wear-resistant, corrosion-resistant and high temperature-resistant ceramic components, hydraulic pressure sealing components can be provided as well.
Properties of Structural Ceramic Ball Valves
Typical properties of structural ceramic ball valves include:
Wear and corrosion resistance
The valve ball, valve seat and inner lining are all made of Hi-performance structural ceramics with hardness of HRA87 or above. So structural ceramic ball valves can withstand the impact of Hi-speed liquids and hard grains, displaying excellent performance on wear and corrosion resistance.
Corrosion resistance
The valve ball, valve seat and the inner lining are all made of Hi-performance structural ceramics. They have been examined by the Metal Research Institute of Chinese Academy of Sciences, showing that the structural ceramics have excellent corrosion-resistance, except to glass-liquor and hydrofluoric acid.
Long working life
The static pressure test showed no leakage after 10000 times opening-closing.
Wide-range of applications
Structural ceramic ball valves are applicable to various acid, alkaline or saline solutions, gaseous media, etc. Hard sealing ball valves can also be used in media with particles and fibers.
