The choice of the concrete connection form is determined according to the engineering condition. Valve for alcohol treatment, the best choice of stainless steel hard seal.Because if you choose to use soft seal, wine will stick to the sealing surface, it is easy to cause damage to the sealing surface. Therefore, it is recommended to use food grade stainless steel eccentric butterfly valve, the sealing surface can be surfacing cemented carbide, more wear-resistant. 316 stainless steel material containing nickel is higher than 304 stainless steel, corrosion resistance than 304, therefore, high temperature and corrosion resistance are also stronger than 304, and the elements containing molybdenum and molybdenum elements of atmospheric corrosion or chlorine element compounds have good corrosion resistance, such as if it is a industrial corrosive medium or is used for the water of the sea, it is recommended to use 316 stainless steel.
