What material is good for butterfly valve

2022-02-15 10:15:02

Die que commonly used materials are gray cast iron, nodular cast iron, cast steel, stainless steel, these several. If the material performance is compared, there is no doubt that stainless steel butterfly valve is one of the best, because its temperature resistance, corrosion resistance and pressure resistance are better than other materials, the environment is also more suitable conditions, the cost of stainless steel butterfly valve is the highest in several materials. If only water and steam are used, grey cast iron or nodular cast iron is sufficient. If you use cast steel or stainless steel, it will increase the cost.

Butterfly valve with what material, medium and pipeline has a direct relationship, including medium temperature, pressure, corrosion resistance, low room temperature environment, butterfly valve gray cast iron, ductile cast iron materials; In high temperature and high pressure environment, butterfly valve is made of cast steel; High temperature, high pressure, strong corrosion, butterfly valve made of stainless steel.
