The ball valve is made of high performance zirconia ceramic material through cold isostatic pressing and high sintering. The components are of high compactness and the size is of high accuracy.
The ball valve is of high hardness（RHA87--92）and mechanical strength with the properties of corrosion resistance, wear resistance and high temperature resistance.
The ball core and seat are made of zirconia ceramic with small friction coefficient and good sealability.
All the sections connected with the media are covered by structural ceramic that has the property of chemical stability and strong hardness second to diamond. So, the valves have many good properties, such as wear resistance, corrosion resistance, erosion resistance, great thermal insulation and small thermal expansion.
The body adopts advanced grinding machine and craft. The ball roundness is of high accuracy and the surface is of excellent quality. The good sealing could be reached by Zr02 ceramic’ self-lubricating when installed with the ball seat.
 It changes the fact completely that the metal hard seal ball valve leaks easily and the sealing surface is of poor corrosion resistance.
This valve has many excellent properties, such as durable in use, high reliability and long lifetime which is 2-4 times as to alloy valve and Monel valve.
This valve has the absolute advantage and it is the unique valve that is suitable for the media, which includes high hardness particles or soft particles with corrosivity.
