Therefore, when selecting valve materials according to the properties of the working medium, it is necessary to study the influence of factors such as the concentration, temperature and heat treatment process of the medium on the corrosion resistance. Stainless steel valves have become a must-buy valve product in various industries, but there are only a handful of valve manufacturers in China that can meet international standards. Therefore, before purchasing stainless steel valves, customers must ask merchants to provide various stainless steel valve production and factory certificates, so as to reduce the purchase of unqualified products.

At present, stainless steel valves and Sanitary Valve valves that meet international standards mainly come from Japan, Germany, the United States, the United Kingdom and Shanghai, a first-tier city in China. Stainless steel valves are control components in pipeline fluid transportation systems.

It is used to change the passage section and the direction of medium flow, and has the functions of diversion, shutoff, regulation, saving, check, diversion or overflow pressure relief. Valves used for fluid control, from the simplest shut-off valve to various valves used in extremely complex automatic control systems, have complex types and standards.
