The ball is processed by advanced polishing equipment that can ensure high circularity, accuracy, good surface quality. The self-lubricating capability of ZrO2 ensures the good sealing performance.Thoroughly free from the defects that metal hard sealing has such as big torque, non-corrosion-resistant sealing surface.

Excellent wearproof property of ceramic enables this valve have high reliability and prolonged lifespan, 2-4 times of that of Titanium Alloy and Monel Metal valve.

Ceramic-ceramic main seal+Graphite assisting seal, The application temperature can reach as high as 500degree.

 It is the sole ceramic hard seal to reach VI level of seals standards in the world.

This kide of valve has excellent performance/price superiority at media with lower corrosion and with particles and fibers or situations with high temperature.
