 5.Material Properties of TZP

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

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

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.

4.Wide application range

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.

3.Long service life

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

2.strong corrosion 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.
