zirconium structural ceramics

zirconium structural ceramic 1.Best price 2.high quality 3.professional service 4. fast delivery

Commodity:ceramic valve

Property:

1.Erosion and wear resistance

The valve ball,valve seat and inside lining all adopt zirconia structural cermaics.Rockwell hardness reaches up to more than HR87,and stand the erosion of high speed fluid and hard particle medium,so it has excellent wear resistance.

2.strong corrosion resistance

Inspected and tested by institude of metal research of Chinese Academy of Science proved its excxellent corrosion resistance,except glass solution and hydrofluoric acid.

3.Long service life

Statics pressure of life tests conducted by Hefei General Machinery Reserch Institute proved that it can stand ten thousand times of switches without any leaking.

4.Wide application range

It can used in acid,alkali,salt gas and liquid medium environments,The hard seal valve is especially applicable to grain or fiber medium environments.

3.Such as:attritor sticks,inner,shaft and sleeves,wear resistant rings and plates,pistons,ball valves,high precision balls etc.

4.We can manufacture the products according to client's requirements.
