How should we consider the material of sealing surface of valve?

What are the factors to consider when selecting the sealing surface material of the valve?
1. Resistance to erosion. Even if the medium flows through the closed surface at high speed, the sealing surface will be destroyed.
Two. Resistance to decay. The stainless steel ball valve is in the closed surface in the medium effect, the appearance has been destroyed the process. Once the appearance is damaged, the sealing effect can not be well ensured. Therefore, once the material on the closed surface is to resist decay.
Three. Under the condition of high number, it is necessary to meet the difficulties of resisting oxidation and heat exhaustion and repeated heat.
Four. The expansion effect of the closed surface and the material line of the body is almost the same, which is more important for the structure of the inlaid ring to prevent additional stress and loosening in the height.
Five. There is a need for some hardness, a great reduction in the degree and hardness of the standard work.
