High Precision Machining Zirconia Cermaic or 99% Alumina Ceramic Ball Valve Seat
Besides some advantages of metal valve, ceramic ball valve seat can also resist corrosion, high temperature,wear and erosion.Ceramic Ball Seat can be used in different kinds of acids bases and salts gas, liquid,stream and slurry transportation system in the industry of petrifaction, metallurgy, papermaking, power station and oil refining.
It is the best substitute product for titanium and Monel valve when it is stronglycorroded.Meanwhile,it
is effective and long time operating (2 to 4 times than titanium valve)with low cost. And it can be driven by
hand, air, spring return pneumatic, electron and etc.As for special valve, we can design it as customers' needs.
